ARAM matchup logic

This is an issue I'm having since a couple of months. Since the main game modes are fucking unbalanced, a lot of people obviously switched to other games or just went down to playing Arams. Which is fine. BUT.

Why is the match making so damn frustrating? Why is the enemy team having 5 tanks roflstomping my team consisting out of 5 supports? Why is there no balanced champion role distribution? Can't you at least make it something like this:

Champion ROLES are random. Enemy team has 3 tanks, so do I. My team hast 4 Supports, so does theirs. Their team has 2 ADCs, 2 AP Bursters and 1 Bruiser with sustained damage, then so do I.

The way Aram is now, is outdated. There is literally ZERO skill or team interaction. Your main games toxiness has begun to invade Aram. I do realize Aram means all random all mid, but that's just a brainless 5vs5 slaughterfest with "whoever has more tanks, Mundo or Vel' Koz wins". It's really frustrating to lose games just because the enemy team consists of 5 tanks with shitloads of CC, while my team is stuck with shit like Ivern and Urgot.

I picked this game up a couple of years ago and already quit the two main game modes. I do like the game, I really do, but the way how unfair matchmaking and how insanely unbalanced the catalogue of champions as a whole is, I see virtually no point in even playing anymore.
