The problem with "Instant OFF GCD" abilities makes combat feel less rewarding.

[Raymeo]

Please share with me a specific scenario where it's impossible to interrupt an ability with either an off GCD stun or Silence due to the animation lock. I'd love to hear it. And whatever you come up with (if anything) I can assure you I can give you advice on how to make it work.

Oh, oh! Let me guess what that advice is. "You need to initiate the stun immediately when the mob uses their ability, so your animation will finish in time to actually stun it. In order to make sure you can react early enough, just auto attack behind the mob until it's time to stun." ISN'T THAT FUN!

If you think about it, this system makes the most sense of all of them. Why should you be able to bash something with your shield while you're in the middle of swinging your sword down as hard as you can on it's head?

Really? I am frickin' holding them in two different hands. That's why.
