Nerf them good! !
Make it so barbs can't use any weapon over level 45, that will really help your class succeed.
Just remove WOTB from the game, and make call of the ancients attack of the oompa loompas, that should help with your classes survival in the higher mps.
While we are at it, cap the barbs aps at .5, then you will be able to facetank mp10 like a boss.
Really what everyone should be doing is thinking of ways to improve your own class, seems everyone thinks that reducing one skills viability will somehow make your class better.
I just hope they nerf it soon, cause I want to see how your class gets better.
It doesn't make other classes directly better. Absolutely nobody argues that. What it does is bring everyone to a more even playing field, and fixes an absurdly overpowered rune on an otherwise cool skill. Barbs still are able to use fury spenders to generate fury. They can still run extremely fast, and damage mobs by running away. They can still no clip through hordes of mobs while damaging them. They will still have the most absurdly good passives, offensive skills, and buffs in the game. Even if they lose 100% godly easymode, they're still an extremely strong class and likely the best.
