Illaoi seems quite suited to the complainers here

P: "Infinite free pets that do massive AoE damage and heal you for PERCENT missing HEALTH"

Q: "Spamable huge range waveclear poke that heals you for PERCENT missing HEALTH"

W: "Free gap closer on 2 second cd that does huge damage and also clears a whole wave"

E: smashes head on keyboard and wails hysterically

R: "Just press it and you get a pentakill and then penta again when they respawn"

Now all she needs is 0.05% health true damage on her R. I'd say she's in acceptable levels of ok right now, which will make threads like these even funnier.
