Fervor of battle change is a very bad idea

Are you ready for lucian to become even more broken than he already is? And for every AD caster to become insanely strong from level 1 on?

Keeping it to on hit damage limits it to only being abused on very VERY few champions. Ill go through them all here

Potentially broken with on hit Warwick Kayle Yi Teemo

The reason why there isn't more is because no one really has on hit modifiers or can effectively build guisinos the way they could before. Kog was changed, devourer is gone, and guisinos is extremely gold inefficient if you don't have a built in on hit effect.

Potentially broken wtih extra AD/will be basically mandatory on these champions Pantheon Renekton Lee sin Lucian Jayce Gnar Hecarim Corki

The reason for this is simply because all of these people have extremely high AD scaling. Especially early game if you just start autoing someone your all in will be insane compared to anyone who doesn't have the same kind of scaling. Changing it to AD doesn't fix yasuo and it doesn't fix ekko. The only things that nerf them have nothing to do with the fact that its now AD scaling instead of on hit damage. The things that are a nerf(as the changes are now on the pbe) are the fact that abilities have a 2 second cd(which could still happen if it was on hit) and that the numbers are just lower so less damage will be added to autos from this(which again could easily happen with on hit damage).

Once again riot doesn't seem to understand what is making something broken and overnerfs too many things/the wrong things in a blind attempt to have balance. Kogmaw is changed, guisinos is a bad item that is only okay on like 3 champions, and the people who are currently strong will only be affected by changes that have nothing to do with switching on hit with AD.
