It all makes sense, but honestly, I think it's better this way.

Honestly, how would it feel if you pushed your Simian Thrash ability, and the animation starts going, then the mob kills you? Now what if you would have won by that weaponskill?

Another example is Chaos Thrust. What if you push the button, you reel back to deal the attack, and you get stunned.

I'm all for damage as it gets hit, but there would have to be different animations depending on if you get interrupted, stunned or killed.

That's a bit much for me.
