Suggest the champion by making List for each roles

Now that we have too many champions to pick from, it's very easy to get confused when I'm looking for a champion.

League has so many champions but the suggestion criteria are a bit outdated. You can narrow down the champions by searching certain roles, like tank, marksman, assassin, support, and so on, but they're not very good.

For example, if you play Leona as support, and she's a very popular support, when you go to enter "support" into the search function, she won't show up.

That's because Riot thinks she's not a support, but a tank. i dont care for it.

but I would like to be able to make my own list for each role, and not have to use Riot's.

For example, if I type "top" into the search function, I can make Irelia, Darius, Gnar, and Volibear show up, or "mid" and see Lux, Annie, Pantheon, Jarvan IV, and Gangplank, all set by me.

Basically, something similar to custom item sets.

With custom search terms, it could get even narrower, such as "top vs. melee" showing Riven, Quinn, and Irelia (my preferences) or "mid against mage" showing Yasuo, Talon, Kassadin, and Zed.

I think that this would be an improvement in helping us pick the champions we want when we can't always think of what to play instantly.

What do you guys think?
