There was some question and answer time including 1 hr of gameplay and 1 hr anything goes. Of course a few questions which had already been answered in guild halls were asked.
I tried to ask Aerilik a ranger question but a monk cornered and monopolized him for 10 min to see if monks could do something like aggression mitigation (basically a complicated way to hold agro). I get the impression that the new AA lines will offer an additional taunt (help for crusaders too) but not sure.
What problems to crusaders have? I play an 80 paladin, and have absolutely no problem with holding hate. I think you mean SKs, which are the absolute suck for main tanks…. or tanking anything over intermediate groups for that matter.
Reading the Shadowknight forum section at the official bulletin boards would fill you in, for sure. ;P
