Combo Action Button

I'm not sure what the problem is here.
No Grit, use Blood Weapon as normal. Pressed Q to activate it.
Blood Weapon on Cooldown. Turned on Grit. Blood Weapon button is replaced by Blood Price button. Use Blood Price. Pressed Q to activate it. Now both are on cooldown.

How would that be complicated? This exact system already exists for Fel Cleave and Inner Beast.

You'd want to be able to track both cooldowns, is all. Mods in WoW, for instance, do this already with an inner radial timer on macro'ed multi-skill keys. A consolidation where two skills' access are mutually exclusive yet do not use a shared timer would need the same.
