I feel like the last-hitting of non-marksmen AD champs should be equal to Mages
I dunno, it just bugs my shit when I'm playing an AP champion like a Mage who has weak AD and is better at waveclearing with spells than farming with autos, but then I gotta deal with an AD champ who gets to farm with auto attacks AND waveclear with abilities, and is usually manaless so they don't need to choose between spending resources to farm or spending resources to harass, they just get everything back to 100% in a few seconds.
Keep auto attacks against Champions the same, that's fine, but I don't think a damage penalty to minions would be infeasible to constrain how much they get to abuse a lack of resource gating during lane phase.
(Im probably missing a few)
