At the moment there is still more benefit for beeing light/staff user because both class and staves damage scale from magicka.
So if you want to go full stamina, you kinda sacrifice your class skills to focus on weapon skills.
The solution in my opinion would be to scale the damage/effects of class skills from the higher stat between magicka and stamina.
Class skills would still cost magicka, so it's not a big game redesign, and I think it wouldn't take that long to make it to the game.
It would probably solve the main inbalance issue that is existing right now between stamina/magicka builds.
