Champ Select UI Proposal

Hi Rioters!

I'd like to propose a change to the Champ Select UI that would improve findability of champs.

Essentially, this system would allow players to "tag" champions with role attributes, which they could then select as a subset during champ select using the tabs at the top of the screen. I've attached a couple of mockup images showing what this might look like to this post, and also included a link to a .pdf on my Dropbox with more mockup, design reasoning, and storyboard.

I know there's been talk about revamping champ select in some way before, but I feel like this would be a really high-value change. Also, as an LIS student concerned about finding everything, it drives me nuts that there isn't more functionality available to the player than just name searching.
