They need a vote kick system.

When something goes wrong a lot of players try to help by explaining different strats. Some players blow up on players trying to help.

Castrum runs I have had healers/tanks afk the ENTIRE instance for no reason.

Party wipes for one reason or another sometimes players are like "You guys suck" and afk the instance until someone leaves.

Sadly, this isn't 1.0 community. =/ I don't really want it to be either, but good portion of this community is rude and sour. They can't take advice. They also explode on other players when it is their fault for a wipe in an instance. It isn't just, "oh crap my bad im sorry lets go again." its "YOU NOOB YOU NO HEAL ME WHY I DIE I DONT NEED TO DODGE I TANK."

I think everyone needs to take a happy pill and get some cookies and chill the hell out.
