I also do pretty much nothing but MH when there’s not a PvE mode running, and I noticed that after the last update as well. I never pay much attention to the rank spread when I join a game, because—well, because arcade—but in my first couple of games I was thinking “WHOA, okay, that Tracer is amazing and 1v6ing my entire team over and over, what rank even are they” for the first time ever.
I don’t mind too much getting trounced by a super skilled player, and I enjoy being challenged, but yeegads.
