Give breaker its own meter.....But the only way I see this working is if its built from taking damage and blocking. The more damage you take the faster it builds. so lets say, a 30% combo builds like, 50% of the Breaker meter. Give it a 3 second cool down after its used before you start building meter for it again. ALSO make it usable anytime during a juggle state and trapped state (Like cyrax's net). even if your not being hit....That way it can be baited, blocked, and punished. You should also be able to break any special move that isn't and X-Ray.
I honestly don't think any character that died in the MK9 story will be returning. And I think the Best thing they could do to Cyrax is make his net have a 7 second cool down ON HIT.
