I’m not sure what you want with matchmaking. We keep going over the entire 50/50 semantics. I asked this multiple times already, but do you think it’s acceptable to have matches where you have a 6-stack of Diamonds and up taking on a full team of solo-queueing Plats? Before you tell me that I’m strawmanning Cuthbert’s arguments, Cuthbert was the first to strawman Scott Mercer’s arguments. And going by some of the other posters on this forum, it seems like there are a lot of people that really do want to rank up to higher ranks but do so by playing stacked matches in their favor rather than playing with and against people of whatever rank they currently are in.
And yes, people deal with winning and losing streaks with matchmaking. You’re playing with and against other human beings. I’m not sure what you’re supposed to be expecting, if you think everyone should be able to “rank up” or if you honestly think that Blizzard intentionally “handicaps” players rather than people honestly trying their best to work with other people despite their differences.
Maybe instead of thinking that Blizzard intentionally gave you bad (or good) teammates for winning (or losing) too much, try working with other people, and use VOD reviews to honestly see what went wrong.
