Still trying to wonder on how is Illaoi any more threatening compared to release?

I'm basically seeing the exact same Illaoi as how I remembered her back when she got released:

• E buffs, that's all I know.
• Q is technically the same.
• W is also the same.
• R is your everyday "I HIT MORE, TENTACLES SPAWN MORE" strat.

But somehow, everyone just tends to complain freely about her everyday about it whenever they got rekt by one.

Something tells me is that it's not the champion's fault for utilizing her buffed kits, it's just the inexperience from not fighting against/playing a lot of Illaoi themselves.
