Zed will do his job (obliterating the squishiest target in sight) well enough regardless of who he has ulted at any point in the game. That AD change will barely feel relevant at any point in the game, except if he fails to ever get a significant Death Mark kill. He's only going to have a bit less AD than he currently has, usually.

As for Akali, those are mostly QoL changes. Also, when has E ever been detrimental? The last time I heard about it it was making Tank Akali a thing.

Fizz will also be a lot better, because his new W actually is a pretty good farm tool. The amount of damage it can deal and the reset on-kill are pretty good. He's still going to be fairly vulnerable to harass, so it doesn't changes too much, except he can survive laning phase without going ham on his lane opponent and praying to God that he gets the first kill before he gets murdered.
