MM has gotten really weird in the last few weeks. When I started, me and my partner won most games, which made a bit of sense since we're both ex-LoL players and have pretty good macro. We climbed pretty quickly and then just started getting games with players who seem very new (like Seeker I) versus experienced players who just go 20/.../ in the lobby and cannot be stopped. I figured some of this was the game trying to sus out our MMR and find the "ceiling" for us, so to speak, but it's been brutal. Last ten games I have a 40% WR and it's almost always one-sided, over at 10 minutes or less, with other lanes feeding 10+ kills in the first 10 minutes.
From last night, this match in particular was frustrating: 73504646
Our poor Yamato went 3/14/5 and seemed very new. Meanwhile, the enemy team Vyper went 25/2/9 and just dunked all over the lobby. They had 88.3K damage, while the next highest on the enemy team was 42K. Our highest DPS was 38.6K. Our team collectively went 16/44/26 with their team at 44/16/81. It just felt absolutely awful to play into.
Another brutal match where their team collectively went 53/15/113 versus our 15/53/15: 73206042
Again, a lobby with a Seeker player versus Ritualist+.
The shift happened around March 26th. It just seems all over the place.
