Practice mode using the original custom game ARAM map

I was thinking it would be nice to have a queue-able or at least custom game mode that allows you to practice a champion 1v1 against another person, where scores aren't recorded and leaving isn't a big deal. It could use the original map that was created for ARAM before the Howling Abyss was made, and when you queue up you can specify if you want to practice top, mid, or bot.

I'm really awful at top lane, and fighting against bots don't help much, and it's never fun to get yelled at for doing poorly in a real game.. so this could be a nice bully free environment to practice a new role in.
