You can't make a map and think it will be finished without a lot of testing and proper adjustments... It takes many hours to complete a good map, so if people are willing to put down the time, both players and map makers. I think some nice fun competitive maps could be added to the pool. The problem is to find serious people willing to test and come with feedback. If you can publish a map on the forum and people would test play and give feedback we have a good chance to get some good maps developed.
The maps could be rated/feedback through different categories. E.g. Competitive play, Fun, Balanced, Dynamic (the map is not a complete mirror from each side). etc...
I'm willing to put down hours of work into this. I already got a long way to understand what's important to make a balanced maps and competitive maps. I still have a lot to learn, I have start tried learn play BNE style maps, so I can understand more what's needed. There is a lot to understand in how to make fair starting positions etc. Also I think a good map should be easy to learn with no special op barrack and tower placements (like in gow).
I also think the competitive part of warcraft 2 would benefit a lot from more 1s maps. But I guess that's really hard without tournaments promoting real 1s game play. Also many players seems scared of real 1s competitive play.
I invented my own system of naming the maps while beta testing them. I add "+" sign to the map name to show that it's a beta test version. For example: Terenas Stand+.pub - Next version would be named Terenas Stand++.pub. And the final version should just be named Terenas Stand.pub.

Would be great if the map pool can be updated and changed often! Great initiative!
