So, I learned something about Illaoi the other day...
I recently played a game of ARAM as illaoi. I was the only person on my team who could reasonably tank, so I went full tank. At the end of the game, I had 4.4k HP from just Randuin's Omen, Dead Man's Plate, and Warmog's. I also had 145 AD with no bonus AD from anything, so because of scaling values, my tentacles still hit like a truck (although a much smaller one than if I went with a more typical bruiser build). I find it interesting given this that I don't see more people playing her full tank.
I also learned that people revived by Yorick's ult (and I would assume a Sion who's been revived by his passive) are treated like minions for the purpose of Illaoi's E, which means combined with his other abilities, Yorick is a strong counter for her when they get equally fed.
is also a good counter to Illaoi. You will out trade her every time she Es. You also bring more utility and damage come mid game. I assume
would work just as well.
