Right now DH has mediocre to low ST damage and terrible AoE and cleave. Were not quite as bad as ww monks are, but were pretty fucking awful. People getting tier sets is actually going to make this problem worse, because ours is so lackluster compared to others.
Couple fixes they could make:
Revert bloodlet to 200% damage, or even buff it to 250% damage, while nerfing the bracers further (so that they're good, but not quite so mandatory)
Buff chaos cleave to 20% damage - doing either of these would probably make the new ring mandatory because we'd be getting so much damage out of that tier.
Revert all last minute changes they made on the PTR - buff dblades back to 100, buff tier set back to its previous levels of crit, and a reduction in fury cost for blade dance. Revert chaos blades to track mastery and be 12s.
Revert changes to blur to allow it to reset stacks of fel rush. Allow momentum to stack so that buff management wont fuck us whenever positioning is crucial.
Give us a flat 7-10% buff to all our abilities.
Any of these changes should alleviate the troubles demon hunters are facing.
They nerfed our burst and gave us nothing for sustained, and its lead to some pretty unsurprising results in nighthold logs.
Or the last option is for them to just leave us as we are and say "at least your not windwalker monks."
