I propose that GAP (Gap of Rohan) is added to the list of maps that are unranked by default.
Setons is given a max allowed rating ceiling of 2000. So you can't reach above 1600 if you only play Setons, unless you are gala.
Both of these changes would cause players to play other maps regularly, which would improve the community and reduce robo players that play the same map to lessen their self-ego.
Lastly, for me personally it would reduce my rating to 1200 ish and I would have more lobbies available to me.
We should also consider 1v1 games played, not in ladder unranked. This is obvious.
