Well on my server I never noticed that much elitism or bad behaviour until end game, even then not as bad as I see in this game. I always tried to help other players, specially if I notice they been shouting for awhile, but that's just me. To me this game is WoWified, so perhaps that is a factor as to me seeing more bad behaviour. I say let them give you a personal parser, if you are using a regular parser then be nice and discuss how a player could improve in /tell with them or keep it to yourself. I think alot of people do not like being talked down to in front of everyone else, it shows no tact to do that.
