Maybe it's just me, but I always felt the quote from the book was delivered better. Probably just because it's all in the mind, you know? Still. http://i.imgur.com/ivPyVYM.png It's a bit of literary genius here. You don't even get to see him say it. You just know the impact.
as an illaoi main this is what i thought of as SOON as i saw her ult XD
The joke . . . . . . Most people's heads
Darius says the same of a J4 when he ults the Dunkmaster. (Might not be entirely relevant to your post, but I can't help but state the similarity.)
I've found you! I expect to get downvotes, but I have a question. Would you mind checking out a rework concept for Morde I came up with? It'd be great to know what you think of it. If so, it's titled, "A random Mordekaiser rework concept."
Also, I can't wait to see the failed hookshots. I imagine they'll be a glorious sight to see.
As an Illaoi main i find op's statement to be 100% likely. I suggest all soon to be camille mains to go toe to toe with illaois during simultaneous ults....there will be much rejoicing.
