@Riot: Illaoi's Tentacles in general are so slow.
The Passive Spawning of Tentacles As opposed to a Vessel spawning one or them being created as a result of her ultimate - both of which are near instant - the ones she spawns from her passive take 3-4 full seconds from the beginning animation (fizzing/bubbling from her idol in her hand) to the actual creation to the point where it's able to be commanded through W or whatever else (the tentacle forming and the 2-strike health bar appearing). This is just ridiculous.
Her Q The swing animation is extremely long, while the hitbox edges are also deceptively small. Make the swing itself faster and make the hitbox indicator a bit more accurate please?
Her W Another long animation which is treated as an autoattack. And for that reason, there's another specific bug with where AS-slows (Nasus for example) will turn her W into a slow-motion 5-second-something long moonjump. That definitely needs to be fixed.
Tentacles swinging as a result of her W or the auto-target on Vessels The tentacles. Swing. SO DAMN SLOW. They are literally a joke unless you are already CC'd or otherwise just AFK. Someone who's disconnected and automatically walking back to base out-speeds the freaking tentacle swings, unless it's swinging parallel in their direction. They are so incredibly easy to sidestep and dodge. Even before the E nerfs, the tentacle spawns as a result of the Vessel were practically useless for hitting the Vessel itself, and were only good for more tentacles for her W. Now, the E is still trash, and had an entire 48 seconds chopped off. Over 80% of the original's duration. Now, I'm not saying 60s was good either, but at least it forced them to keep moving around for a bit longer. Right now, it's literally just "AFK, and then take a single step to the side whenever a Tentacle spawns". And, yay for them, now it only lasts 12s. The indicator pops up and the tentacle swings, but both of them take so long it's an absolute joke. Make the swing-speed scale off either her level or passively, off ranks on the W or E or whatever else.
Her E Wooo, another ability that's been killed by a change. Being a Vessel means literally nothing as stated for the above reasons. Either increase the base time to something like 30-35s flat, or make it scale off E rank. If it scales off E rank, something like 12/20/28/36/40 would be a good start.
Her ultimate Yay, the main source of QQ, except maybe her old E. Except her old E's been neutered and is dead. So now this is it. Yay... Yay for a jump that takes several seconds before the actual hit even occurs. Yay for being a complete noob-trap that means nothing because anyone with half a brain would just walk out of the zone or split apart in different directions so she can't just maul them with tentacles.
Yay for the 10001 something bugs and incredibly long animations resulting in crappy cancels Because all the animations take so long, literally almost anything can interrupt them, canceling them mid-way and randomly putting them on cooldown or not. Either way, this makes her kit incredibly annoying and irritating to use because you can't even rely on getting a successful ability off thanks to all this crap. Another thing is, apparently, she's immune to displacement during her ult. That still doesn't help people just canceling her ult before she can even get the tentacle spawns off because they just stop her mid-jump because the animation lasts so long.
But yes, sure, she obviously needs nerfs, Riot. Because she's totally been a problem, having never gone above 49% winrate. And not like the E changes dropped her 5% to 44% or anything.
