I could be wrong, but I feel like anyone who can't be bothered to put any effort into playing the actual game is probably not hanging out on the forums. The people you're complaining about are very likely not the people who are complaining about elitists. There are players who will ruin your good time at every level of this game, though in my experience they're not that common. If I run into a player doing something that drives me nuts, I ask them to stop, and if they don't, I typically just leave. I'd rather do something else for half an hour than get aggravated about a video game.
One trend I've noticed recently is that (presumably new) players, often tanks, will not chat or even apparently read the chat. People in the party will notice that they're new and give them tips for the boss, which they utterly ignore. And like, that's fine, I don't need to have a super-optimal run to be happy, but when the tank eats a Lunar Cry twice in a row after we've told him several times how to avoid it (and presumably he can see everyone else, including the other new player, hiding), I kind of wonder why he's even playing the game. This isn't "striving to be the best" or improving or anything, this is literally understanding the gameplay at all.
