hey I'm trying to figure out what the best weapon to use for ds heroic to maximize dps as a boom kin
Rathrak, the Poisonous Mind and odd hand Dragonfire Orb or[Visage of the Destroyer] or lighting rod
I think it all depends on your current haste needs. If you could use the haste from Lightning Rod to get to a major haste breakpoint, use that. If you can't reach a breakpoint easily, use Rathrak+offhand. I'm pretty sure both these options beat out Visage, though I'm not positive.
