I like the idea of changing the map pool.
We should consider 2-3 new maps created by skilled players with map editor experience. Together, they should test and change all maps considered for 1s and team games.
Also take away unfitting maps from ladder, such as skull isle, HSC BNE or mutton
etc.....
Once new maps are ready and approved, they should be played in tournies so that players can get a feel for the maps and decide if they are fun, interesting. Then vote for the final map pool.
