@cocAurico Yea, there is a bug where the 2v2 queue is using your 1v1 rating when selecting the map: https://github.com/FAForever/server/pull/702. This fix will be deployed during the Feb. 13 server update.
Like FTX said, it also uses your trueskill mean, so not your displayed rating which is mean - 3 * deviation
. I checked your ladder rating which is mean 1882 and deviation 65. Since 1882 > 1800, this explains why you got a map from the 1800+ map pool.
