Balance matchmaking system?

Mostly every game I've played, has had really poorly balanced teams, with the enemies always having the higher ranks, vs our team with low ranks. Not blaming it on my team, not their fault, but maybe at least balance the mm so we get an equal amount of mmr/elo in each team? Shouldn't be that hard anyways knowing how long league has been around and how there was no such issue last year about the mm system. Although it's just norms, I play it to practice new champs and combos, which is really hard to do when the enemy has pretty high ranked tryhards (in norms btw) and riot can't manage to tweak the mm system a little bit and balance it out a little bit.
