Illaoi's Passive might be too RNG-based.
Currently, Illaoi's passive on the PBE causes a tentacle to spawn nearby on a wall every 20-12 seconds, the cooldown based on your level. However, if you get a bad tentacle placement, you have to wait a long time for a better one.
What if the cooldown on her passive was slightly increased, BUT, everytime a tentacle hits an enemy champion, the cooldown on her passive was reduced? Tentacle hits would include her Q, as well as her passive tentacles. This way, you get rewarded with more tentacles for playing well in lane.
But I don't know. Thoughts?
EDIT: And what about tentacle hits on jungle monsters too? This would allow her to have a viable jungle clear.
