DK is tanky as heck, so shouldn't be buffed much or it will be broken, but SO MANY of its skills have been butchered. Look to dragon fire scale etc. It feels like its lost its flair a little as the slow pressuring bastion that can reflect damage and needs tactics to fight, think darth vader in rouge one. I originally was hoping for a sorc style cremation execute passive, because it would synergize well with the dots, but I doubt its going to happen.
Dragon scale nowadays is useless, it costs way too much, for 4 seconds and 4 projecties. Half the things aren't even reflected. Now take a look at wardens where it dishes out more damage/gives ulti, and returns magicka. Needless to say, flaps need fixing.
On a slow class its rather unfair to keep out gapcloser behind an useful pve skill, I say separate chains into a gapcloser (chains) and a pull. (Stonefist) This would be done by renaming stonefist "tectonics" and instead have a fossilize style root come out from the ground and pull them. On a similar note, pulling automatically grants cc immunity. It shouldn't. Instead it should be able to be broken out of, allowing people to pull sorcs out of the mines without them scurrying back into them like sewer rats and having 6 seconds free immunity.
Inferno, used to be a cool AoE. Now its a shitball. Decent for pve as a dot, but rather useless in pvp since it is once every 5 sec and untargeted. And the heal morph is utterly attrocious. Heals a single person every 5 *** seconds. It is the worst ability in the game without a doubt. Make both AoE. One morph poison miasma, and the other to be 'consuming inferno' that applies mag steal on targets.
Aside from that, (and maybe the health recovery passive wtf) DK is in an OK spot.
