Have you ever played D3 whirlwind? It’s smooth and aimable. One key starts whirlwind and the mouse/controller steers it in real time. Also it stops and starts with the skill button. I think that would be the way it should play but also follow D2 old rules for speed and breakpoints. Get rid of the clunkiness altogether. They have that code available to them. Why not use it?
A while ago I found a 2H windhammer for my barb and started using it.
Even if I socketed it with a shael the amount of hits that I am able to land is disappointingly low. The damage and CB is decent but killing monsters doesnt feel any faster than using two tyrant clubs with black runewords. I used 225 strength for it too
