Mirage's "Revive Buff"

Don't get me wrong, him cloaking while reviving is great, however players are now able to revive faster than lifeline. So fast that I can make a mirage stop reviving and then all of a sudden the person is back up, even though they stopped the reviving. I expected there to be bugs, but letting Mirage be Lifeline on L-Star bullet spark power level is insane.
