DKs in MoP

[Shodokan]

So I know death knights too a major blow with the loss of blood tap among other things but i was wondering if people still play them and if so what kinda changes theyve made since the release of 5.0

Blood tap is the best ability in the t75 tier... so you didn't really lose much in that department.
Oblit is hardest hitting ability even on plate
Need to adapt to using howling blast when rime is up

DKs still do the most damage of any melee in the game minus a warrior during recklessness.
