Complete imbalance for Aram teams, please fix!

The first thing that pops up in my head when I start an ARAM game is, who is playing what and what role do they have part in this game? I notice immediately my team is comprised of either all AD or all AP champions, so I think rerolling will help give us SOME sort of balance. However, the moment I reroll, I get stuck with the option of another champion of the same damage out put (AD or AP). So then I look closely at the enemy. 3 ap, 2 ad, or 3 ad and 2 ap. Seems like they got the balance for their team, how are we suppose to build against them as a complete AD or Ap team?

Then I look even closer at my team... 4 melee ad and 1 ad ranged (Me as an ADC champion), and then I look at the enemy teams champions.... a cho'gath AND a teemo. This just became completely one sided, great. So not only do we not know how to build against any of these champions because we are all AD, our team is comprised of melee who are completely countered by 2 single spells (Cho'gath silence and Teemo blind).

This is becoming a bit of a nuisance. As much as I like playing ARAM, it seems like luck isn't even a factor anymore with what team you get, you're just matched with a team comprised of one sole factor: AD or AP.

Please fix this. I have quests I need to finish in ARAM but I can't seem to win any cause' of my horrid matchmaking.
