What I meant was that they can adapt if and when the fight is undone. The reason I added damage to it was that you considered it potentially useless if it functions in the way it does. The damage may be high, but in most situations where you'd get a lot of damage out of her ultimate you have probably already won the fight anyway. Sure, if you burst down the enemy ADC, Mage and Fighter, then the ultimate will deal 20-25% of their max HP. But to do that damage, you have already taken down the 3 main damage dealers of their team. Doing it again but slightly easier serves little purpose.

But as I seem to be slightly underestimating the advantage gained from the ultimate, I'll reduce the damage.
