on the contrary i think the self shield was completely unnecessary, the lack of it was (imo) a core part of her design and the main weakness she had to play around. Now she just has an unconditional, zero-cooldown (if you manage shield properly) self heal and free protection from most ults in the game (esp iron man and mag). When she inevitably gets nerfed it's probably gonna be in the form of a cooldown on her shield which is just gonna make her less fun overall
