If you want quick, balanced games, then go to ranked. You can found a new game within some minutes. Match making will make sure teams are much more balanced compared to the lobby.
1v1 ratings are pretty accurate in my opinion. So almost all 1v1s are pretty close. TGs might be much more unbalanced, but i still think it will be much better then the lobby. Unbalanced TGs is the result of a calculation error in the elo calculation for team games. More about this issue:
I am pretty glad the devs added ranked / match making to DE. Match making is much superior to a lobby in my opinion. I once tried the lobby, but is was a terrible experience. So i never went back to it. I also notice most of your complaints. Match making solved most of my complaints.
So i see the lobby as place for some niche maps, playing against friends, for tournaments, stuff like that. If you just want a quick balanced games, then the lobby isnt the place to go. Ranked is the place to go.
