using ktm, i see when people go overboard with threat - so overboard that they just make it near impossible for me to regain aggro, so i have to throw everything i have to regain it. I do- but its lame, it wastes my mana and they should know when to back off.
A guildie caster was doing that and eventually died and i had to save the group. I was the last man standing. Bubble , seals, judges ftw!
I said "back of a little, let me get aggro more", however it was too late for them =[. They learned after that one .. didnt wipe or anything but made it a difficult shatt halls run.
