Pretty much solo, yeah. Chat channels are worse than they ever were, almost to the point that it makes me miss old Barrens chat.
I was doing Maw of Souls the other day, and the tank just dragged everything, fuck the classes that need to stand still a full 2 seconds to possibly get any enjoyment out of it. He clicked on the horn after the first boss before anyone had a chance to even loot the boss. I called him on it, and the response was some "get in ur mail later" or some shit. OK...or..OR, you could wait 5 seconds for everyone else, you know, a shorter time than it took to reply to me.
Because I'm an idiot, I still try to help out others in game, like if they're in trouble I'll join the fight....only to then see them run off and gather/loot/leave, with me having to fight all the mobs then. The only time I see some nice teamwork (outside of dungeons where you have to work together unless the tank is way overgeared) is when I spec blood for invasion points. I just go gather up enemies, and let others have their AOE fun. People still go in there and don't turn off pet taunts and the like...which is fine 95% of the time, but funny with those bosses that do some sort of area damage (lava, ground spikes that cast like a fel lightning, etc). I'm trying to taunt the boss to a safe area, and all the pets ruin that.
