The whole bad dark knight thing is not the class it's every person not coming from a tank background thinking dark knight looks cool im going to swap to tanking
Give them time to learn there job it's still a new class and tanking ain't the easiest job right out of the gate
Positioning ,cool downs , and holding aggro should be there main priority but a lot of people think that dpsing as a tank is what there meant to be doing
Dpsing as a tank comes in time with practice but should only be done if groups need it which is rarely needed
I think people will think different once savage Alexander is downed and farmed pretty regular and the dark knight rotations start popping up
