so i'm up to lvl 22 now and i've seen some of the issues that people have been talking about:
1) tank who doesn't know what's up; was pulling aggro after every heal because the tank wasn't using the group aggro skill (flash i think). then he'd just ignore the one attacking me and keep on trucking with the mob he started with. this turned out to be just new player syndrome though cuz as soon as i explained it (nicely) he straightened up and everything was gravy.
2) the asshole; different group from the first one; this guy was playing DPS and just wouldn't stfu about how slow the group was, how shitty the other DPS was, how the tank wasn't pulling enough mobs at a time and my fav (and new to me in all the MMO's i've played) how much healers, as a group, "sucked dick" and shouldn't be in the game.
we had a little difficulty, since it was 3/4 players first time, in copperbells where you have to use the bomb to split the green thing and man did this guy ever cry and cry and start spamming "FAIL!" into the chat.
it makes me wonder what kind of person is sitting behind the keyboard, to pay to play a game where you seem to be taking out your lifes frustration on people who are just chilling and playing a video game.
anyways; tldr; there's real deal assholes and there's some people who just don't know what's up. i find being nice to everyone is the way to go. although i'd have let that asshole die if the tank wasn't so damn good.
