I noticed that SE added a lot of recast-time reset/reduction mechanics to various jobs in SB, and I'm honestly at a loss as to why they didn't implement any of these on DRK. DRK is one of the only jobs in the game that has no personal % damage dealt buff window they need to line certain things up with, and so recast-reduction/reset mechanics would flow better with it than most jobs, compared to WAR for instance, where the Infuriate mechanic is neat on paper but a bit awkward in practice. I feel that DA and TBN reducing the recast time on things like Shadow Wall or Delirium would make the job really fun and add in a mechanic that is actually rewarding.

I mentioned earlier in this thread (and I feel like it bears repeating) the idea of dialing back our combo GCD potencies a bit and instead introducing recast reduction mechanics for mana checks like DAC&S, thus raising the skill ceiling a bit, and offering us a DPS increase for more attentive mana-consumption (plus letting us C&S more often would be really satisfying). I think as far as personal DPS boosts this is one that would not only be really fun and more interesting than bland potency increases, but also reward higher level play in a way that the job is simply failing to do at the moment.
