[1.2.322] Moar Skill Balancing

It would be way overpowered. Consider Aran. Their formula for booster is: boosterLevel = -1-1*u(x/10)

So levels 1 - 10 give -1 booster, levels 11 - 20 give -2 booster, level 22 would give -3 booster

This would give all mage classes -1 extra boost, +1% damage to base stats, +4% mastery, about +5-10 WATK more, longer stun, burn, poison duration on all skills, higher crit rate... higher EVERYTHING. It's like the ultimate everything booster.

They could just add diminishing returns to ANY skill over max level.

That's exactly my thought. As in, lv 20-30 give less per SP than lv 10-20. They'd just have to tweak the new increases for levels above.
