As other people have pointed out, looking at the loading screen can get rather boring. I was thinking that while you're waiting, you could move your cursor over any of the champion boxes and click on them to receive their stats, lore, tips, and other things that are given to us when we click on a champion portrait in the shop or on our profile. Any thoughts?

this is actually a great idea!
i say this, and whoever you have selected be animated (like how new champs are, in the loading screens. miss some of them lol)

Interesting add to this. I like the whole animation idea!

Alt tabbing is the best way to go. Just go read reddit for the 3 minutes it takes.
