Random number like 3/4ths are fun. I believe people would exclude others for lack of quests just as much as they do for lack of gear. I've had plenty of noobish geared players in my VW runs that performed their proc function. It's when people get bad reps as being noobs for not having relevant skills or knowledge of the content they are trying to participate in that usually gets them excluded. I've never once claimed to be better than everyone else and you wouldnt have a clue if I was or not, none.
You don't understand that if you decide to limit content to your acceptable standards there will still be others who feel the bar is still set to high. To do what you are suggesting means the bar can be no higher than the ability of the absolute least skilled player in the game. I have seen people fail to kill a mob using multiple brews. In effect you would have to allow full time brews in all zones all the time and eliminate "K.O." in game. This is the only way EVERYONE can be guarenteed the same success rate.
I'd love to see those who grief others eliminated but until SE takes a harder stance on this it's simply not going to happen. I reported a guy for /yell "I just got (random number I forgot) Ni**er shells." The GM did nothing, the player remained in PJ laughing about their "play on words about T. Whiteshells." I'd love to see these types of people removed but again thats on SE.
Until SE simply does not allow certain accounts access to content everyone who plays does in fact have access to all content/gear. Access to, and guarenteed success in content are two very different things. When my LS was building empys we ran accross a lot of other LS's who had 10~ relics between them, we had 1. Their WAR had an armada hauberk, ours had an adaman hauberk. We would watch them fail and struggle with mobs we killed much easier. Gear does not determine outcome, at best it allows more room for error.
I would love for everyone to experience the game equally, this is exactly what my post is asking for. I want people to be able to enjoy all content on their own terms of difficulty. The part you disagree with is where I suggest harder content should have better rewards. SE absolutely needs to keep making content that is AVAILABLE to everyone. What I don't want is for the difficulty level of all content to be designed only for those who struggle with things others might find easy or for SE to predetermine 100% success for anyone.
P.S. There is always someone who will think the content is too hard unless its 100% win/drop rate.
