Ability level up previews

One thing I've been hoping Riot would add to the game is to include what each level of an ability adds prior to having the level available. It'd be nice to see this ability adds 50 damage per level and this one only adds 40 but the mana cost doesn't increase. Or this ability increase my stun duration but this gives me more damage.

These changes would have a bigger impact on newer players and learning new champions. I have way more games than I'd like to admit but even I could make good use of this on champions I'm not so familiar with. It's just easier to decide during some downtime on your way back to lane rather than when you level mid fight.
