it'd be really nice if riot would have a place to go where you could select a champion and select 6 items and have it display the final stats and damage and such. it would save a lot of time and would be realllllllly helpful.

i know that the information is out there, and you can easily do the math yourself, but it would be really convenient for most players to have this to easily make a build without having to try it (and probably having it fail) in a game.

Exampe:

You'd be able to choose Morgana and select 6 Archangel's Staffs and it would tell you the resulting ability power as well as how much each one of your spells would end up doing.
