Reverting of Champions @Riot

Can we please get a revert on certain champions and items? I feel like a lot of them have become more and more difficult to balance ever since Riot has changed them

Example A: Kennen: He used to be balanced (annoying as hell as always tho), maybe instead of changing the ult so much during the mage rework, they should've just bug fixed it. Revert to old ult and bug fix it. It was super inconsistent. New ultimate is just flat out insane cause let's be honest.

Example B: Nidalee: Revert her to her to 5.2 and start again, if more balancing necessary. Amount of nerfs are just out of control, and she was fine before.

Example C: Rylais: Didn't this used to be balanced? This is causing champions like Kennen, Syndra to be broken

Example D: Vlad and Swain: They've actually caused more problems from the rework, and the rework didn't seem to be done very well. Maybe not revert the entire rework, but do something about the cancerous mechanics (granted they're not too bad to deal with right now).

Please do not hate me, these are just some suggestions, as a fair amount of balancing and reworks have caused more problems then that were originally there.
