I do believe taking the shrouding from turrets off is plenty. Her Q heal is a sustain that she needs seeing how she is to be played. It's not much at all and takes a considerable amount of time to get off a Q that heals decently. Especially when it requires full energy, you can't even get the heal off in a fight unless you possibly shroud and gain enough energy, even then hitting 1 champ won't give enough of a heal to change the outcome of the fight. I say the Q heal should be kept as is.
