For the sake of variety also for strategic purposes. If there were no AD casters then it would enable more standardized counterplay methods to all casters that would make AP casters less viable.

Zed dealing AD damage through his spells is fine. Assassin's don't auto attack alot. They get in and burst the target and get out. And not all of them are AP so it's not really anything interesting to observe. It's just the very basic way this game has come to design champions.
