[Suggestion]Borrow a Champion
I was thinking that it would be really cool if players were able to borrow champions from a friend/other player/PVP.net for a single game. The borrow mechanic could be on a 24 hour timer or a recharge bar like the re-roll mechanic for ARAM. It would be free to borrow from friends, but cost a small IP fee (maybe 100-300) to borrow from Riot directly, again with a cooldown.
I think this would benefit both Riot and players. Many times, people want to try a champion before they buy them. This way, a player may not have to wait for a free week to play a certain champion, and it might also encourage people to spend RP if they like it, since they can only do it so often.
Any thoughts?
