Uneven Matchmaking

I've been playing a bit of Flex Queue lately with my friends and for some reason, we've been getting ridiculously outranked in games. We're mid/low gold/low plat. We're consistently playing against high diamond players especially when we're in promos. One game we played against a diamond 3, 2 diamond 4's, a plat 1 in his promos, and a gold 4. There was another time where we played against a diamond 1, diamond 2, and a couple plats, 1 gold. There are plenty of other examples, and I don't understand how the matchmaking does such one sided match ups like this. I don't mind losing, but it gets pretty irritating to consistently get matched up against players 2 tiers higher than you.
