Dark Knight

Can you please fix dark knights hp to damage. I made a dark knight before pink bean so they were very helpful because of hyper body for zak and ht. Clearly they are not needed anymore since everyone is washed. My suggestion is to have zerk active at all times even at full health. But take down the damage increase from 120% to like 70% or something like that. The reason because whenever Im at half health for zerk to be passive. I have a hard time bossing and die very often. Even at 30k hp. I have friends that are heros and palis and stand there spam hit skills and have full health and do twice the damage as i do. I believe dark knights are the most useless character in the game and are not fun to play anymore. Im a level 142 dark knight with very decent gear. Thank you.
