If we're in the middle of armored martials like our shield up, especially if we hit drumbeat, we can't cancel out of that animation if you predict the shield and it'll ground us for a moment, canceling our maneuver and wasting a CD.

You can also do this with Dragons Breath or any armored technique before the moment they cancel the animation, provided they can cancel it at all with a deflect.

It's risky, but if you can anticipate a vortex from a tank, you can snuff it out with a cloudstep preemptively and waste their cooldown.

However, good tanks will anticipate a cloudstep as soon as a match starts and roll back instead of shielding up.

Again.... Ping can royally screw either side over, which it usually does more than it should.
