Illaoi's E feels so bad now
Before 6.9 it felt god awful for the vessel, now it feels god awful for Illaoi as it went from 60 seconds to 12 seconds.
Yea 60 seconds was really long but 12 is too short.
Let's give her the Darius treatment, 12 seconds --> 20 seconds.
You can change the tentacle spawn rate if need be.
Also on a side note if Riot does decide to buff her besides reducing the W cooldown, maybe decrease the amount of time it takes for her to spawn tentacles late game so that she can actually fight with more tentacles by her?
