For me DRK is a very fun tank to play, but there are some things pissing me off and just don't make any sense. To start with, both the other tanks have some kind of ultimate defense skill, DRK's ultimate defense skill " Living Dead" is hard to use especially in PUG situations. 50% of the times i've used it i died cause healer didn't notice it to fully heal me. Of course you can use macros warning people etc but a lot of times even that won't help.

Next, the MP management issue, the amount of focus you need to have in order to output good dps and not to run out of mana is stupid, they could have made the whole process less annoying. A Lot of DRK's just end up not using half their skills cause they cant be arsed to MP micro manage in every pull, it gets very tiresome after some time.

I believe with some balance between those 2 factors DRK will be in a perfect place to play.
