Orochi is already capable of choosing when to strike with his storm rush. Is it possible to make all his heavy attack able to be held? (just like charged attacks, except the longer you hold it, the less damage it does) So if people play with a HUD. There will always be a red arrow indicating an attack from that direction while its being held. Now as a negative aspect. You are in attack mode. So you lose your ability to parry and block. But you can still cancel back into reflex or dodge out of it.

This I think would give Orochi the opening ability he needs. Instead of feint. He makes you believe when he's actually going to strike so you prepare your defense, second guess yourself let your guard down and get struck.

Tail end idea. If Orochi dodges left or right while holding a heavy. He does a dodge heavy attack in that direction?
