Can't be bothered to quote so i say it again, 2 days is not enough and this wont last long... I agree with zoxxe ideas, dont worry i didnt miss any of them.
You say you played 13 maps in 2 days, well done with your achievement, but what makes me angry is your opinion to leave everything as it is as you see 2 day progress...
The thing is, it all depends on the players. We can't force them to play other maps, so we're trying to get enough people together to try to encourage players to play different maps. It's been working pretty well over here on the NA side. On Monday's and Tuesdays for the last 2 weeks we've player AA3 Alley, AA3 Impact, SF Blizzard, SF Water Treatment, mAAp City Block, mAAp Square, SF PCR, 285 Interdiction, AA3 Shantytown, and some others I can't quite remember.
The point is, if you take the initiative to try to start a server that plays different maps, people usually do join. You just need around 3 people to get things started, at least that's how it is for the NA side.
