Indeed, brd dps is at least 100 points higher than mch dps right now for me, ilvl 227, horde wpn on both. When I get lucky with bloodletter procs, it's actually 150+ difference.
Considering how brd has always been better in a multi-target scenario, I think it's a little unbalanced. I'm wondering whether hypercharge is still better than foe requiem as a support skill
since battle voice cd has been shortened, I'd like to see some math on this, but I suspect it's no longer the case. Still, I believe brd is trickier to use, especially in fights with a lot of mechanics that force movement
so who knows, maybe the buffs were adequate.
