Dark Knight feels pretty overwhelming.
This isn't a rant, not at all. I just wanted to throw in that coming from a WAR main, DRK has a hell of a lot more to watch out for, I find myself going into a brain fog managing mobs, CD's, MP, positioning (for mob AOE and such) and still find I'm forgetting to throw in Scourge more often than not.
Probably my only nitpick is that Low Blow and it's chance to reset ahead of it's timer is screwing with my mental clock for rotations.
A versatile class to be sure but I definitely wouldn't recommend it for first timers looking to get into tanking. Unless of course you spam Unleash and then just siphon to death ( which I'm pretty sure isn't the intent)
