Crazy idea for reworking AD champs and crit

What if we changed all Assassin, almost all ADCs, and all other AD bruisers scalings around?

Assassins only have bonus AD scalings.

Almost all ADCs have only bonus AD scaling(few exceptions could be Ashe W or Draven Q) and made it so crit scales on bonus AD?

For example what if crit did bonus damage based on your bonus AD? What if crit does 300% bonus AD on top of your autos(so if on live a Draven with 400 total AD would crit for 800, with this change he would have 300 bonus AD which would make his crits deal 1000 damage)?

AD bruisers and tanks could have their spells and abilities be changed to total AD scalings to make changes, I'll use Darius as an example.

Let's say his new ult does 100% total AD at 5 stacks instead of 150% bonus AD. If we use his current scaling live without any bonus AD from anything besides his passive he will deal 900 damage at 5 stacks. I cant remember his base AD at level 18 so let's use 100. If his passive isn't changed for the steroid his ult would deal at 5 stacks 900 damage at 300 total AD(base stats plus the steroid from his passive). Say the Darius had 100 bonus AD before the steroid and got 300 bonus AD with, his ult would deal 1050 damage if my math is correct. Now if we had the total AD scaling and he had 400 total AD(god forbid) and ulted he would deal 1000 damage.

What does this even do you might ask? Well not only can it make balancing a little easier for Bruisers, Assassins, True Tanks, and ADCs but it will make it unable for Assassins and ADCs to be able to abuse Bruiser items as much as their damage takes a massive nose dive without bonus AD.

All of these ideas might not be great, none of them, or they might all sound great, I want to hear your opinion on this idea!
