Aram NEEDS a change already....
With the recent "mana" band-aid to ARAM it hasn't really done anything to the game mode. I still find myself losing game after game after game because of either bad team mates or bad team comps. My team fighting skills are absolutely amazing, but I can't do anything if 3 champions on the other team are my counter. Time and time again people have begged and pleaded with you (Riot Games) to change this game mode, to make it something better.
The only change that can fix this game mode 100% is giving EVERY ACCOUNT access to ALL CHAMPIONS while playing ARAM. This fixes all the unbalanced teams, and biased team fighting teams. I have lost maybe 30 games and won 10 aram games in the past few weeks BECAUSE of smurf accounts. When you start losing MMR because of a game mode and not because of player skill, something needs to be looked at.
