I think that's your problem : You think it's a ladder. It's not.
To be fair, the wiki lists the auto match maps as the ladder pool, FAF lobby lists tutorials for the ladder maps , everyone calls it the ladder and most rts game i've played use automatch for ladder plus there's a 1v1 leader board. So It looks like a ladder , works like a ladder and is called the ladder, I can't be the only player to think it was a ladder.
The real competiting system is the league and divisions boards.
I can't find any information on the wiki/forums about the leagues and divisions. Does it work similar to the Starcraft II leagues with promotions , demotions and new seasons? how do you get points in the leagues, through auto matches? and does player rating effect anything in the leagues or how many points you win/lose or games needed to advance? forgive my ignorance if this information can be found somewhere, i couldn't find it.
