So, Illaoi.

Can we tone her down? She was already borderline broken in the right hands before you massively buffed her, but now you went and removed any kind of counterplay she had, and massively buffed her already huge strengths.

Before, you could beat her if you controlled the tentacles, and dodged her Q + tentacle swings. Now, since she has % max health damage on her W, she can just kill your spirit anyway (tentacle or no), and then beat your face in with no tentacles around and still win. And now her tentacles do twice the damage they used to, and just one stray swing is enough to make you lose a fight.

So, take away the % health damage on her W, or revert the tentacle buff, and she'd be fine. But right now she just has too many strengths and not enough weaknesses or windows of opportunity to engage on.

But, hey, that's F2P. The whales couldn't figure out how to play her effectively, so you went ahead and made it so that any moron can play her and do well. Kudos, Riot. Sure do know how to penny pinch.
