Customizable Champion Select Categories

note: There's a poll below. If you think this is a good idea, let Riot know by voting. Often, when I am playing mid lane, I find it inconvenient to have to sort through my champions when making decisions about who I'm going to take in mid lane. "Mage" and "assassin" are two separate categories and take extra typing and thought to switch between and sort through, and they don't even have all of the mid laners. I think it would be easier for champion variety and non-interrupted thought about the champion select if there were customizable champion pools. The title for the champion pool and the method of choosing would be similar to the item set feature. For example, if I wanted to pick out the champions I feel confident with and I have a high win rate with, then I would select the champions below: I could set it to the string 'winrate' and then in the search bar, I would search "winrate" and those champions would show up. And if I wanted to respond to more specific situations, I could say "mageCounter" and make a list of what counters mages, since I'm deathly afraid of mages who are good at doing what they do. Or further, "purplechampion" or the like. I think this would be good for champion select, and it would definitely help my peace of mind. Because really, I think we're all exhausted of sorting through our champions.
