i feel like your assessment on some of the lower scope champions is too cursory. Specifically Zed's change is pretty massive from a viability standpoint. Zed's ultimate currently gives him 20% bonus AD while his new ultimate will focus on his enemies AD. Right now Zed can guarantee, if he wants, 5 damage items that will average about 300 AD between them giving him a minimum bonus of 60 AD if he wants. The new changes to Zed will mean that if he goes against a super low AD building team comp (top Jax, jg sej, mid lb, sup zyra, adc Cait) and the adc builds a crit focused build, warlords mastery with IE, runnans, PD, steraks, GA and boots for a very defensive build, you will essentially only get around 200 AD max meaning that he loses about 20 AD but if he goes against a riven building 300 AD he can gain as high as 80 AD (from what I know it scales with total AD of the enemy so riven could give you like 400AD). This means his viability into super heavy magic damage comps is lower but his viability into high AD focused team comps is higher.

As for Akali, from what I can tell, while it may be small, she is getting a new blink attached to her W, and her E will no longer be detrimental to her kit. This means she will finally have actual disengage to use.

Fizz's laning phase is about to get somewhat better. He won't necessarily be 'good' but he will be able to farm which means more consistency amongst fizz players in their ability to get gold and thus snowball.
