The content structure promotes guilds, the core of the game. People come to a guild because they are hoping the guild will get them aotc or vault rolls. I think the solution is to let pugs go wild. The only toxic pugs are the limited range of pugs that give some grindy checkbox reward that too many people feel obligated to chase. Just spread all that out over the whole content range and let people farm it at their own pace. All the pressure comes off the pugs, all the pressure comes off the guilds, everyone can play how they want, and no one has any specific motivation to be salty in their play time.
