Hahaha oh manYes, a little.
I feel as if the wording SHOULD notify the BG if he's attacked by the illusionist. The wording says "Disguising is treated as a "normal solo killer attack" for the purposes of being blocked."
Which by my understanding would notify the BG that he's blocked an attack. Or taken an attack. Not that it was an illusionist or anything, but I feel they SHOULD be told based on that.
