Change the interaction between anivia's q and spellshields
Anivia's q has two damage instances. The first one will proc spellshields (for example banshees), and the second one will stun the target. The spellshield is almost useless against anivia. I suggest, that spellshields block anivia's q completly, to add more counterplay to her kit. Anivia is arguably too strong at the moment.
