Item sets was a fail, but what about champ sets?

Dear Rito,

The "support class" encompasses a very marginal amount of viable supports. Give me the option to determine who is a support and the option to filter my champions in champ select so that I can view the supports I deem worthy of the class title. As it stands, only Marksman gives the player the ease of viewing all of your options at a glance. Expand please and thank you.

P.S. It would also be nice to implement mastery rating into champ select. Seeing level and chest/no chest would be nice, yeah.

Yours truly, A dedicated support player
