Self sustain would be nice, as would more DPS, but ultimately I'd hope it doesn't complicate the existing rotations.
Personally, I don't care if DRK is easier like the argument back in 4.0 - tanking should be easy, we don't have enough of them and the desire to play them is rather low for queues. Even if we pumped all of that extra DPS into well-placed buffed Salted Earth attacks with some vulnerability bonuses, it'd help buff up the attacks of others for a limited period. It seems like Salted Earth is the ideal ability to indicate to the team to push DPS since it's one of the most noticeable attacks of the game.
