Uh, why are you bringing up PTR? There’s literally a barb build on PTR that breaks the number system and posts infinite (as in the symbol ∞ ) damage. And it isn’t a single ∞, its multiple Undecillions (as in 10^36) of damage. All from thorns/WW and the new passive.
Of course it won’t make it to live, but PTR is not an argument you should be making, at this point. Barbs can break the game in PTR.
For your reading pleasure: ∞ Infinity Damage
