Broken ranked team matchmaking?

I'm sorry if that has been covered before. I'm an average player who just started playing ranked team games. The first game was great. Got matched with/against ~1000 elo players. I managed well and we had a respectable victory. The teams were well balanced. I did most of the kills, if it matters at all (I didn't get carried). You'd think I'd get matched with slightly stronger players after that? Wrong... This is so far from what happened. Strangely, I'm now only matched with very low elo players who lost nearly all their team games and all their solo games. And the opponents have a respectable ~45% win rate over hundreds of games. Can't remember their elo, but it was higher. I didn't lose to end up in this situation. It happened overnight after my first game. Now I end up carrying my teams really hard to no avail. Last game was on Black Forest and the flank on the other side didn't wall. So I signaled them. They thought it meant to send a single milita poke the opponent's wall... I still can't unsee the two villagers corpses near their boar. I'm a team player, so I went all the way to wall them myself. I'm usually hosting "noobs" games, and I've never seen this stuff happening. People usually know what they're doing. The games are a disaster. It's almost always a 1v4 scenario. The teams aren't balanced at all. This is frustrating, because even with about 3 kills for every unit lost, I'm not winning the 1v4 war. So the system lowers my elo as a result. Bringing me further from games I can enjoy. I'm sure it's better with 1v1. Well, it's surely better than the 1v4 mode... I've found the team matchmaking really disappointing. A player winning at around 1000 elo for their first game should not be paired with 600 elo teammates later. I don't think I'll play ranked teams anymore, as it seems more like a source of frustration than fun. Is it a known issue or is it just me? Can I hope things get better as I play? I guess I can be forgiving, since maybe there are just not enough players to create truly balanced teams. But it still doesn't make me want to come back.
