3's ranked matchmaking is bogus

Why is there no matchmaking in ranked 3's? It just pairs you with whoever and vs whoever. You know how annoying it is deciding to play 3v3's and starting your climb through the ranks when you get a 3v3 plat 1 ranked player while your 3v3 rank is bronze. meanwhile i have this dude who is ranked in 3's plat 1 eating the ass of these plants with hands playing on my team. I love 3's, it's fast paced, more coordinated, easier to get a group of 3 together and better than the trash lp you gains in solo q once you hit dia since riot decided to rape anyone who abused the shitty positional ranked system and fuck anyone who go there after the fact.
