Please add scaling information to champions with items

Basically title:

I would like and I think many would like it if items on champions showed dynamic changes to the abilities of champions similar to how it works on normal LoL.

IE: 2 Star Garen does 65 magic damage each pulse for a total of 585 magic damage. Slap a Morellonomicon on him which gives him 20% more spell damage, it would be nice if that was reflected when you hover over his ability to 78 per tick for a total of 702 damage over the duration.

It would give us a better idea of what items actually do to the abilities of the champions and if an item actually is beneficial on said champion, especially for those that may not be as intuitive like Graves, Kassadin and Vayne abilities.
