I decided to fully address the rest of your post, the social elements, in an entire separate post, because I feel you deserve to be listened to and this is a wildly different subject than what I addressed in my other post.
Honestly I just chose not to play with those people. It's a fairly simple solution. If you perform truly unforgivably badly and don't listen to my advice and attempts to guide you through how to play better, I'll just blacklist them and never invite them to a raid again. If a person play really well, OR listens to my advice as I work with them to help make them a better player without getting angry or defensive, and is open-minded to improvement, they get Whitelisted and priority invites back to my raids.
I'm not elitist or anything though, cause folks who perform to at least 80% of what I would consider "theoretical perfect execution" (a pretty generous number TBH), or are willing to learn and show improvement, and are not otherwise toxic (like you describe), get graylisted. They don't get priority invites back to my raids, but they also aren't banned and are welcome to come back anytime.
I've had immense success with this technique in every MMO I've played. It is not quite as good as GDKP for producing extremely high end skilled pugs, but I do not feel I have a reputation on my FF14 server strong enough yet to attempt to convert people over to glory that is GDKP pugging, as people are often initially very hostile to the idea before they realize it works, and then they beg for more. But without first forming a spine in the local community, I cannot ask people to trust me as a GDKP leader.
So until then, the Blacklist, Whitelist, Graylist system is my best bet.
I'm female, and I usually view Tanking as a nurturing mother-bear sorta role protecting my cubs, as opposed to a tough-guy standing up to folks role. I've also had a long history of tanking alongside other women in raids (nearly 5 times as many as males), and almost always have male healers. (Both of my boyfriends play healers, one girlfriend is ranged DPS, and a random female friend who also plays with me is a tank. Hi poly person here)
So from my perspective, tanks are women and healers are male. To me those stereotypes fall on deaf ears with me. Don't know if that changes your opinion of me. But I do have intense respect for healers, and respect for you based on your posts. Because this is a specific hot topic for you, I've made a conscious decision to suppress my standard Karilynisms that I traditionally use for everyone, and not to address you as "darling" or "sweetie" out of respect for your feeling that such feminine terms of endearment are patronizing.
Since I generally expect all my players to perform at the same level, IE as close to perfect execution as I can reasonably expect without being a jerk (mistakes happen, all is forgiven, as long as we admit them and work together towards a common goal), I'm not exceptionally accustomed to tolerating an environment where DPS are being carried by healers. However, it seems like you're accustomed to this being the norm. You're bitter, and you are 100% right, you have ever single right to be. That's shouldn't be the norm, but for you, it is the norm. And that's not right. You shouldn't be subjected to that.
That's been the core of my entire argument.
If DPSers are playing well, it takes this incredibly unfair stress which has been put on you as the accepted norm, and removes it from you. It reduces the pressure. It gives you more room for smaller spell-choice mistakes without wiping the whole raid. I wish you were on my server so I could see about whitelisting you, and bring you along with me for a few times, and learn what it's like to not be carrying this ridiculous unfair burden that you've been carrying. And maybe, with time, help ease the bitterness, so that you can have more fun. You deserve to have DPSers who put in the same amount of effort as you do.
The burden of performance is on all of us. A raid should be a team. We fight and live and die together. We conquer together. And we all have a common goal. Nobody should be carrying the weight of others. We cover each others' mistakes, we help and support one another, but we do NOT demand others account for our laziness. We cover for each other because nobody's perfect, not because someone isn't trying their hardest.
And if in every raid, all 4 DPSers were performing even 80-90% of what you're describe yourself as performing, I can't imagine the burden on you would be anything less than halved.
I don't think I ever said that, and I'm truly sorry it came off that way. It tears at my heart that I said something that upset you so greatly, through my own poor choice of words. Please forgive me.
My address was intended to largely one of saying that Well-Performing DPSers and Well-Performing Healers are in a similar boat, and that Well-Performing Tanking is a laughing stock in this game compared to what DPS and healers have to deal with. It is not you who is the over-glorified tank babysitter, it is the tank who is the over-glorified baby that needs to be taken care of (This coming from a 12 year tank). Neither Healers or DPS can eat damage, that was a huge part of the purpose of including the Healers in my Titan's Earthen Fury chart.
In the sorta situation you describe, with Horrible-Performing DPSers, of course your job is astronomically harder than it has any right to be, and without a slightest doubt by an extremely extremely wide margin the hardest job you can have in a game.
And it should not be that way.
This is 100% unacceptable in every way shape or form. In a raid with well-performing DPS, the burden on you should be lifted enough that you are no longer as stressed as you are. Healers generally chose to DPS, not because DPS can't beat DPS checks, but because, you're no longer under this ridiculous pressure and burden of carrying others, and have more free time to stand around because you aren't constantly having to pull DPSers asses out of the fire, and can DPS for fun because there's nothing better for you to do.
That's how it should work. That is the only situation I find acceptable.
I know, that's the same way I feel about playing a Black Mage. A lot of people toss shit around about how easy it is, because the basic rotation is the simplest of any DPSer in the game (though not nearly as loleasy as Paladin, ugh.). But if you truly try to min-max it out, and achieve the highest theoretical maximum that's humanly possible, the payoff is incredibly rewarding, and the challenge is deeply satisfying in a way I haven't felt in an MMO in many years. I'm starting to enjoy the difficulty of being the second most fragile class in the game (After White Mages of course; we're otherwise identical, but I have Mana Wall, Mana Ward, and Aetherial Manipulation to give me a slight edge), cause it forces me, like you, to play almost perfectly in order to not die. I'm coming to enjoy the difficulty that comes from Black Mages absurdly and borderline obnoxiously nailed to the ground, a trait we both share, so I'm sure you can appreciate the forethought that goes into timing your spellcasts to minimize interruption during heavy movement fights.
Those fringe benefits are bullshit, and don't pass mustard around me. I don't tolerate tanks who swagger anymore than I tolerate DPSers who cluster-fuck defend their under-performance. In my ideal raid, every player has pressures equal to every other role, and everybody pulls their weight. (That's why I wish Square would make tanking more difficult in this game; there's virtually no current in-game situation where a tank will EVER be under the same pressures as the rest of the raid.)
+1 for respect, polite communication and education, and helping people learn from their mistakes. I often try to add in things like "We all make mistakes [playername] darling, no anger is here to be found today," or "Hey there [playername] darling. This is probably your first time on this fight, because I noticed that you didn't seem to know about [insert obvious mechanic here]. Don't worry, nobody's angry, we all went through learning at some point. Here's what you should to do next time. I believe in you! Good luck sweetie, you can do it! <3"
A positive response to something like that, gets a whitelist. A negative, defensive, angry, or toxic response get's a blacklist.
Optimism, encouragement, and positive communication and acknowledgement of specific things performed well, as well as specific advice addressing specific problems, fosters more success than anything else. I also enjoy addressing people as individuals, it makes them feel more valued and encourages them to try harder.
Nobody performs well in a pessimistic, angry, bitter, negative environment. I try to give a reason and a belief and a hope that the party can fight together towards victory, a reminder that we're all allies on the same team, not enemies of one another, and through this I can get most players to give me 110%.
