Syndra can W the Vilemaw

Like in the title, I found a bug with 's W. In fact, you can't W epic monsters (Dragon, Baron) but you can with the vilemaw. I don't know if this is normal, but it's pretty weird. For a 3v3 player like me, this is totaly horrible when you fight for the vilemaw. Enemy's W and no, you cant get it ! Anyway, I'm reporting it, I reported it, so, I hope that will be patch :).
