Eve W and Spellshield

My understanding of Spellshield: When uses W on someone with , Banshee would go on cooldown, Eve W goes on cooldown and nothing else happens. But apparently W is not considered a hostile ability. She can use it on you without proccing (or / Spellshield). What is even more interesting for :if she uses a spell to procc the charm the spell will be blocked and the spellshield removed but the W mark remains on you to be procced. Only way to defend vs her W is for her to try and procc it with an auto attack when your is still active.
