[Gameplay] Normal queue MMR behaving badly

Three games in a row now I, (Bronze IV), have been matched with teams (in Normal queue) that have at least one player Gold V or above, if not more than one. We're talking my team of Bronze/Silver against an opposing team that has well matched opponents, and then 1 or 2 ringers. One game had a Plat, one a Diamond, and one had a Gold V/III duo.

I realize Normal MMR and Ranked are separate, but do I really get matched against Platinum, Diamond, and Gold players vs my team of Silver/Bronze? Their Normal MMR can't be that far off their Ranked MMR.

I did further digging and found that 2 recent opponents have a 95% and 97% win rate across their last 20 games...that's just astronomical. Something is clearly misbehaving with MMR right now.

I'll take my licks and keep learning, but it seems I'm being matched against some seriously stacked odds and the learning curve has just gone off the deep end.

Edit: For reference, I was playing with a premade team of 4 and 5 for the first two games, and the last one was a solo queue.
