Idea for how to make Illaoi less annoying and less of a "Bad Champ"

Illaoi is honestly a very cool and interesting champion who I like to play as, but tend to honestly feel useless if anyone I face has some competance. My ultimate requires me somehow getting into the middle of the enemy team despite no gapcloser, my ultimate isnt primarily a flat aoe dmg one but rather a dps ultimate that I can get cc'd while using or the enemy can just walk away. Late game I feel like the main thing I become is an E bot hoping to land some super mean poke through my team killing the souls with me (which if they are not an adc/glass cannon mage is like the only way to kill one again), but then why not just go full tank blitz top so my grabs are death causing instead of just poke.

However, no matter how bad Illaoi is most people will find her obnoxious due to her E. The vessel thing is so strong/annoying and forces a lack of interaction between players while the enemy has to dodge the tentacles they spawn. sometimes the lane is boring until you finally land one E and kill it, and then farm while the enemy deals with it, and maybe u can chain it together too so that they are never not vesseled.

I propose an idea, I know riot may or may not see this but if they do I hope they could think about it at least. This idea is to change her E up a bit.
The new affect when the spirit is killed is you are rooted for some time (maybe 1-2 seconds, idk) and nearby tentacles attack you just like currently.

Now the two key differences is that 1: you do not spawn tentacles anymore, which means you can actually lane against illaoi and she has to aggressively position/fight you to create new tentacles, rather than her afk farming while you play dodge dodge revolution for 30 seconds so you can kill 3 tentacles. The second key thing is it gives her a single target, highly situational cc that allows her to actually do damage to whoever got caught in her e before she ults, which is needed as her damage is linked to stationary tentacles, and doesn't have the benefit of a walking execute burst-ult like darius or garen.

I do hope something like this is considered, because as much as I love this champion/character, I only enjoy playing her with friends who build a wombo combo comp with aoe lockdown just so I can feel useful. Even crushing the people who dont know how to fight illaoi doesnt feel satisfying. All in all, a dps but stationary dmg source with no cc to keep them nearby is nearly useless. Hell if she was somehow made AP and I could build Rylais like mordekaiser she might be fine, just make tentacles, ult, and the w bonus dmg be magic dmg.

Regardless, I'll proabably be one of the few that still plays her, cause honestly a good Illaoi ult that maybe someone gets stuck in for some reason will be one of the most satisfying and epic things in league.
