I wish the abilities' tooltips in-game show you the full stats of the ability at all five ranks

Wouldn't this be a super helpful? Specially when you play the champion for the first time.

At the bottom of the tooltip it should tell you all the ability's stats at all ranks (like more damage, more mana cost, more CC duration, less CD, etc) , rather than just the current rank.

It would be also more helpful if it shows you the exact AD/AP ratio of the spell as a percentage..
