What feels the most unbalanced beside the obvious 3-4 poison rush combo?
Pain Doll, definitely; primarily its fast cooldown.
Bleed seems underpowered; I’ve never seen any bleed builds that seem like they survive into the endgame. Poison ends up beating it every time, even though people have shield, because poison scales so much faster. Even if you lean into bleed at every opportunity, and have a board full of bleed items and bleed boosters, it isn’t fast enough to outpace damage-rush or high regen or poison.
It feels like bleed is balanced well for the early game; it just needs more scaling.
