3v3 flex matchmaking

I feel like the matchmaking should take into consideration the overall experience of the game like ranked solo q and ranked flex 5v5. It's been too many times that I (gold V solo q and a spectacular bronze 1 in flex 5v5) get to play vs a master in solo q (plus diamon I in flex 5v5) just because we are at the same elo in 3v3 (around gold I). I know there are not as many people playing 3v3 than 5v5, but i really enjoy playing it and it's just unfair getting crashed with no chance of winning. I'd rather wait an extra 5 minutes and get to play against players my level. Let's be honest for a moment and realise that the diamond/ master mechanics are way better than a low gold mechanics. It seems too me that Riot itself ignores 3v3 queue just because the 5v5 it's way more popular, but there are still people trying their best in 3v3. And there is one more thing that is very annoying. Sometimes the diamond player looks you up and sees your elo and just brags all game in chat like ''im diamond in solo q kid, i don't even care about this game''. That ruins the whole experience of the game.
