Yeah that's pretty silly. But we all know seph isn't excactly healer tight, there is many times you can sit in cleric for a while and do it, not that I will expect it, dont even need the extra dps unless its super tight somehow. Well, for me, it's NOT acceptable to kick someone whos doing 100 ish less than they should that means they are pretty good more than an average player. If they are doing 500-600 less, then I would ask them to leave, because you can't leech around me and get free pass by kills. The fact what you mention is just pure stupid, doing 350 ish as a whm is even good, but you know whats even worse?Those who think they are godsent but are even worse than an average players, those players usually ruins it for many as well. I'm pretty sure you know what I talk about. I talk for my own personal experience, many times I've farmed and we just go on with a guy being 50-100 behind, but if someone is way behind then that person has to leave, simple. I know there will be people kicking out those who are doing great and isn't the top but how many? I rarely see it happens, atleast around on my server. Keep in mind I've also been on Ragnarok and Odin server and you know those servers has one of the top players on Eu servers. But yes, I'm sorry if I ask again sir, but could you kindly explain to me how people could know how they improve in the actual fight/content? I talk about using SSS method, because you and I we both know and I sure hope so :P haha. That SSS doesn't give you any spesific data you actually do in battle content.
Many will be left out even without official parsers, because it already happens. Many are left out for reason and you and I both know very well why.
I'm not gonna defend some peoples shitty attitude on these forums, so I will only speak for myself. I'm one of the healers who dps alot in expert dungeons, my tank pulls till the wall is stopping us and that's it. I'm not gonna expect people to do the same when some one else is healing, after all my motto is; best tank mitigatation is a dead mob/boss. You want to talk about toxic people? I have a bunch of many different scenarios like the BLM that refuses to use fire 4 in dungeons and go with bliz 3>fire 3 and it's funny to waste peoples time. Or the Tank who doesn't even overpower adds and let me die as a healer because regen is on, because they say that's how they play. Or that one healer who overheals and has no mp for next pull and blame it on the tank. The list is long. I could go on all day about this matter, but I rather not.
Edit: I wanted to add, why look at the negative sides of a parser when it's the last thing that puts a negative thing into the community? If you want to look at the negative side of everything, dont do trials, roulettes, talk in chat, or do content or even interact with people, let me tell you a secret... they might be bad people?! Shocking right? :P
