This video of 6 minutes and 30 seconds explained just about everything I've experienced from others in multiplayer games for years.

I just wanted to play the game and have fun, not aim to be top in damage meters and be criticized when I don't push to squeeze out every bit of damage I can do. I just wanted to do stuff, but there was no way that I could in an environment full of people that demanded too much from me. Now that I have moved to a Japanese server, I don't have that problem anymore because the players are more understanding, not all of them, but there are far more of those who are concerned about others than not. In fact, now I have the problem of the opposite, there's too many things to do and not enough time to do them all, and I end up feeling overwhelmed if I don't focus on them one at a time.
