Does Illaoi Need a Rework?

She's been released two months ago and has a 45% winrate.

Her tentacles do an absurd amount of damage (200% AD ratio with maxed Q). But outside her annoying (REALLY ANNOYING) laning phase she is a non factor. She can obliterate an entire team if they sit in her ult but they have to sit there (and they won't if they are not stupid) and she has to be able to reach the center of the enemy team with a 350 units dash.

Riot is buffing his E (the spirit pull) mana cost but I don't think that would help. And outside laning phase is a pretty useless skill, it will do some damage and thats it.

His kit is too binary, get a good ult or get kited for ages. And getting a good ult is really hard. But buffing her mobility or stickiness with the amount of damage she does would be crazy.

I think she needs some big changes.
