thats why i wrote there are enough ppl queueing (thats also why i chose the 20-29 bracket as an example, prolly the biggest skirmish bracket except endgame obv)
edit: people who win 50% of the time, people who win 60%, 30%, 20% etc so it shouldnt match up people with high mmr with people who would have 1k mmr due to their win/lose ratio
edit2: maybe skirmish at endgame does have a hidden mmr but i dont see why blizzard would even implement that for lower brackets, most brackets alrdy have horrible 2v2 skirmish qtimes (even the xp on ones) and it doesnt require much brain for a pvp designer to realize that mmr in such small brackets would be even worse for the queuepops
