The official Matchmaking blog post

Reads like - Hello, we are cluless, Matchmaking is * but it will be even worse, enjoy and fu fr

"When the matchmaker is trying to form a match, it grabs 60 available players of similar skill and tries to form a match"
Srsly, nobody by now believes that crap anymore, or Respawns definition of similar is very very broad.

also bcs : "There’s always a range of skills in your match." sound very contradicting to me ?!?!
"However, this skill gap should still not be large because we limit the range of skills in each match."
muahahah, that was a good one. how is it possible to outperform your mates tenfold if the gap isnt that large ?a lvl 50 with 10 kills is clearly not the same skill bucket as lvl "3000" with over 5K kills on the legend, but the system keeps dealing me those consistently.
"To be fair, the following is not exactly what happens in the actual algorithm, since we also need to consider queue times and other variables outside of skill rating. "
What are those other variables ? I would love to know ... this only opens the doors for speculation about it beig rigged.
"This number is intentionally hidden from players to avoid exploitation."
Aha, other games seem to have no problem with telling your skill rating  ... must be some hell of a system that can be exploited by one number.
Afaik the ELO of every tournament chessplayer is known, and i never heard of wide spread exploitation there.
"In combination, the effects above can certainly give the impression we are intentionally doing “big brother matchmaking”"
im still not convinced that this is not the case, with all the contradiction and hidden values playing into the whole thing.

Well, I've just been afc'ing for the last 10-15 percent while face palm'ing. I was like, bruh, how are we losing, I'm out here MnK-style movement on controller, PK'ing people in the face. My guess would be because kl on their team has as many kills as my 8 teammates put together. Love the balanced mm.

Update: We lost.

@r1ggedgameThey aren't going to tell you that. I want to know what they consider in the skill rating calculation. Not gonna happen.

1/25:  Did they revert any test region changes or is the current Collection Event geared towards the Chinese New Year just pulling in all sorts of cracked or cheating players?  Holy hell the matchmaking went into the toilet in the last few days!!!

Have they changed squad matchmaking again?

I played about 15 rounds last night and in 8 of them, my two squadmates were downed in less than 1 second of gunfire and did close to 0 damage. All 16 of them would have had a combined damage of under 100. The worst squadmates I have ever had. It wasn't like this last week or the week before.

An interesting take-

Ok, but explain how i play casually with a level 200 and one level 100. With their highest rank ever being Gold. Mine been like diamond 4 one time. Playing against full stacked preds? and getting stomped 10 games in a row by masters. * behind this game.

@aisthebestletterNot from what I've seen, especially for premade parties of 2 playing Trios.

Taking the highest skill rated player in that duo, matching them with a random (often lower skilled for some reason), and feeding them to premade Diamond/Masters trios is absolutely horrific. Even if your random is higher skilled, I have almost never seen them be able to carry that duo against premade trios.

My brother and I do the duo in trios thing and it is a horrible experience. Totaly ruins our attempts to play this game together and often gets us ticked off at the game &/or ticked off at each other. We'll disband and play solo and instantly have better matches, too.
