Cait's attack delay isn't the problem. Her traps and Hurricane stacking made her near pickban level.

Good job on getting rid of Hurricane nonsense crap.

But why nerf AS DELAY (not even attack speed, the delay part) which just makes it feel incredibly bad to play her? That's not even the problem.

Her traps are the problem with how horribly oppressive they are which is one of the biggest issues. She has literally no excuse to ever lose lane provided a decent support outside of jungler influence. Even with jungler influence, she still has an overwhelmingly powerful presence both early and late. Her mid isn't amazing but it's nowhere near bad enough to justify early and late.

There's a reason she was practically pickban in any competent tier of play and has seen play through every single tier at massive amounts while maintaining extremely high winrate.
