I don't know if I agree with the solutions offered, but I definitely do want to add my voice on Imperator. This is an off GCD ability that has something like 2s of animation delay, preventing you to do literally anything else (beyond moving). Cannot recuperate, cannot purify, cannot guard, cannot anything. I'd understand if it was a channeled ability like Honing, even a LB, or whatever where you commit to it, but here it's just an animation delay where your hotbar just looks frozen for no reason, and it feels terrible. Not only this, but the skill also unlocks Confiteor, which is a SPELL, so it's on the GCD. Having an oGCD button turning into a GCD button is certainly a design choice alright...
