Maps and MMR question

Yet why wouldn’t they apply their TrueSkill variation per map?
It should, in theory, improve your accuracy.

The reason I was asking is this btw.:

This isn’t the case for most matches on console right now (that’s a fact), it could be the result of having groups in all of the games (not visible) or the result of limited player pool in two of three roles forcing yet in a lot of matches both teams ranks per role let alone per team don’t match.

Its based on the assumption that your skill varies greatly due to the map you are playing on. Map specific hero selection (some maps benefit your go to hero more etc.) and in general how people usually have no clue on maps they played rarly on yet with each additional match might tend to perform more steady.

Ive also noticed how most of the maps Ive played rarely on or are new tend to be placement matches. This could either be due to a low degree of confidence in skill or flawed perception on my end.
