How does game matchmake you for 8 player FFA matches?
It doesn't seem to depend on your comp SR, since I would (almost) always end up in a game with most people being platinum and higher, while being mid-high silver myself.
It also doesn't seem to be based on level. I've been to quite a few games with level <100 people while being level 160ish myself or ending up in a game with 2-3 silver bordered players.
Is there some special FFA MMR? Is any info known on how it is calculated?
