8% I think would be solved with more feathers procs not with pot buffs
if there is that much discrepancy in the damage its the kit in its self not just pots
This is why I say more feathers and better procs, back in ShB you could get procs separate for each weaponskill
I don't see that in the new dancer but I also think they should have a heavier ally buff
this way working with bard then fight with them for dominance
But overall BrD should do more dmg just how much more is the question
