You'll get the d-bags now and again. Its just the nature of the beast. This is my first MMO as well and I rolled a gladiator too... Boy did I get a rude awakening! LOL!
I took advice no matter how rude it was, watched videos, and read like I was studying for a college exam! Ive come a long way since then.
What ive started doing is if someone
pops thier mouth off at another party member and gives them a bunch of grief like the OP stated I blacklist them. Theres plenty of more people to pair up with in the DF.
As a matter of fact in Revenants Toll today someone shouted how to start a quest cause they couldnt find the quest giver. The response: "go to system, click exit game, turn off computer and throw it on a 4 lane highway cause you dont need to be playing this game."
They were immediaty blacklisted. Why even say that. Of course the shouter with the question then said "you guys have fun in endgame, im out"

It just makes me really mad sometimes. Sorry for the rant.
