I have to agree with this, as a tank i have to spam defensive cooldowns to get them to work because if i just press the button once there is a very high chance that it will not actually work because of some animation i'm in the middle of, like rage of halone.

This game has implemented both animation lock AND a GCD on abilities (though not movement), the result is a great deal of unresponsiveness and delayed effects which force us to spam buttons until it finally works. I strongly recommend getting rid of one, and since combat is balance around the current global cooldown it seems getting rid of the animation locking is the better solution. You don't lock our character in place for animations, don't lock our abilities either.
