More champs for ARAM

My idea, to have all or more champs unlocked on ARAM mode. It's not perfect, but we don't get to choose who we play except by trading and what champs are available. So, why not?

Why have I thought of this, after over a thousand games of ARAM I always see the same long range champs over and over. You know the ones, etc etc, champs whose abilities extend at least a screens length. This in my opinion defeats the purpose of playing a random mode.

Rotating (50-60) a greater number of champs would allow us to practice champs we don't have, force all of us to play champs we don't like at some point, and to have much different line ups during game play.
