Currently it is about 3-4 position, so it could make it into the top 3.
For 1v1s:
This time it is picked by the devs.
So it really depends who picks it. Sometimes it is by the devs, somethings it is by the playerbase.
I dont think pros do like MR. For this reason you cant really find much about this map. At lower levels this maps is a bit more popular. At least so it gets voted into the map pool for this reason.
