Can Illaoi's tentacles slap faster when she W's without ult? Or give W a strong but quick slow?

Illaoi currently has many issues facing her. She lacks mobility to get in to ult, she lacks cc so that even if she gets off a good ult the enemy can run away instantly unless she has friends helping. Most importantly though, she lacks general reliability even if an enemy is in her area. Her Q is slow skillshot that is potentially easy to dodge. This is relatively ok since it hits pretty hard but has a fairly large hit box. Her e is of avg speed for a projectile skillshot which works since it is a very reliable way to potentially get a lot of dmg off on someone, and it can poke them quite low if she can kill the whole spirit, however the vessel time is best described as an annoyance to the enemy that they just have to deal with but has few major consequences usually besides maybe an exp deficit due to waiting for it to go away before dealing with Illaoi (although i must admit, the few kills gained from the vessel state are always hilarious and fun part of league).

However, her W is unreliable as a damage source (besides the auto itself) due to just how slow the tentacles swing yet this should almost be her primary reliable dmg ability. I have watched/played as illaoi vs a tahm kench (who has a large hitbox) and he was able to sidestep my Q and my E and walked at me while I was near a tentacle, and the only damage I could do was the damage of the W auto itself, as he could sidestep the tentacle proc. Similarly, I have pulled the souls of other enemies towards me while i am near a tentacle, and they just walk at me and dodge my Q and the W tentacle proc and just fought me until the soul disappeared winning the total trade since i only dealt a percentage of my actual dmg.

This as illaoi feels very wrong. You are supposed to have a zone that you try to build up and are strong in ala heimerdinger, and yet, this zone feels like a fake shield because I need to ult just so the tentacles can actually hit something, meaning I need my ult on a 30 sec CD. As a champion, I often feel like I cannot function unless I have frozen mallet or IBG, and even then the slow is rarely enough. I have never played a champ that felt so incomplete without a singe item that I almost have to build it first/second no matter the matchup or enemy team comp. Even when she ults she has reliability issues but at least you can often guarantee one round of slaps before they run assuming they lack a dash or flash. Either faster attacks from tentacles or a strong but short lasting slow ala darius W on her own W would solve the issue. An illaoi with 3 tentacles on walls near her cannot garuntee any of them will hit if she W's a person who is by her, and its her strongest weakness but in an almost unfair way (i had to wait nearly a minute to set up those 3 tentacles in that area, and you just walked in without care almost).

Just hoping something happens so that illaoi feels like more like Garen/Morde/Darius. Sure they lack initiation CC (they only have short range cc in darius and morde's case although that requires he have rylais.... but at least that alone solves his reliability issues usually) while garen is just really fast/tanky, they at least when they get in range they can do their thing decently reliably. However, Illaoi (and by extension her tentacles) being in range doesn't mean her damage will hit. Whether this reliability needs her to lose damage or something i am not an expert on, but feeling like you cant control your own ability to do damage is frustrating.

I still enjoy her even with her issues, but such a change would make her far more satisfying and I hope its at least being noticed/looked at. Thanks for reading if you read it all and hope you have a fantastic day!
