Let's face it.. the Achievements tab will never be used.. So why not simply make it into a skin library to view all the skins you own like the champion library.
Or another idea, how about an item library, or a way to select a build before hand like setting your own recommended items?
It's not a major problem or anything that honestly needs fixing however I just feel that these suggestions wouldn't require that much work to be honest and would also be very useful.
Just my 2cents.
