I have to agree with Callo on a few points, it can get a bit confusing at times. When I left, earlier in the year or last year, the 1v1's moved from CM to Good Grim, when I came back they were at GTR.

Why did they move from GG? It seems like the most logical place on the map, it's not too far from GV and the creeps have the GG map in.
