@Riot A suggestion on Mage changes perhaps?

so while we're all waiting for Riot to give compensation buffs to mages for the loss of certain runes (mainly MPen and scaling AP afaik) along with reducing MR across the board, I was thinking maybe instead of just giving everyone +5 damage to all abilities, I was thinking that at least for some champions, instead increasing the AP ratios on some abilities would be better to maybe give better incentive to reaching late game. I don't know, it's just that some late game mages just feel rather underwhelming late game; maybe that's just because of late game AP itemization, but when I play Karthus, who is quite possibly the definition of Late-Game Scaling Hypercarry, he just doesn't feel as impactful as he should be at times. Maybe giving him slightly higher AP ratios would help in this case.

I'm sure some other champs would benefit from this kind of change as well, champs who tend to fall off late-game and could possibly use something to help keep them more relevant in the late-game.
