I know its ARAM is suppose to be all random but i wish there was some restrictions you had the option of placing.
Like if you could have an aram playlist where it would only choose from a user selected pool of champions, but your playlist has to have 50+ champs on it that way its still pretty random, you just have a degree of control.

Or it would be nice if there were bans to say no one on either team will have the possibility of randomly getting any of these 6 champs
