PoE 3.21 Crucible Wither, Chaining builds

Compared to my previous builds, I brought in Windscream and Despair to help with the damage. I have so much movement speed from other sources it being a 20% MS boots instead of 30% just doesn't matter. I honestly see no problems. I have no flasks but I do have 190k boss DPS. Without Despair and Wither and no boss config PoB says I still have 98k DPS which is plenty for act clearing. This entire thing doesn't take into account the 10th projectile. The biggest cost on the entire build is the need to have 2R2B somewhere and we have no good candidates for that so eit
