In MedianXL, Windform was never a main skill for barb (due to median's monster density, a skill need to multi-hit a lot or have big aoe or both to become a main skill). Windform aoe is very poor, doesn't multi hit a lot, it didn't proc anything.
But with Sigma, now Windform finally proc, everything, on hit, on striking and on kill!
So, my theory is to create a Windform barb, which a lot of "on melee hit" proc to deal damage to large aoe.
For "on melee hit" proc to happen, you need to hit monster with weapon swing, and there is a limit to attack speed that other build can't exceed.
But a Windform can hit one monster 2-6 times (depend on weapon attack speed - only attack speed of the equipped sword, no other speeds matter), so if you hit like 6 monsters with 1 windform, that's 20+ hit with just one click, and he gonna proc a lot if you constantly windforming.
I can think of 2 ways to make this build works: Poison proc and/or Weapon damage proc
What do you think? Can a build like that work in Ubers?
