To be honest I do feel some maps should b removed. Some aren't up to standards in my opinions. I'll give some examples:
-Insanity Cause: Extremely unpopular map, the pvp is pretty terribe and it isn't the most fun to look at. It is also overly difficult to traverse.
-SG Japan: Also extremely unpopular, I reasonably lie this map but the unexplainable lag tends to turn people off.
-Freeze Island: I know this map has work put into it but did we REALLY need it? It's like breeze but with ice chases instead of water chases.
-Fortress Pyke: I thnk this map is beatiful and well built but its getting less and less popular and isn't really needed.
-Moonlight Lake: There are some interesting ideas here but overall the map is poorly built, like you cold build this map with Worldedit and VoxelSniper in about a day. I just feel that the quality isn't up with mcsg standards.
-Kahmanrah: This is actually my favorite community map. But it has problems, some places are terribly built and put togather and the size and terrain make it hard to find people. It too is losing popularity I and I think it's a candidate for being removed.
I know some people may disagree but we really do need to start choosing maps mor carefully or mcsg's standard coud fall. Sorry if I sound all high and mighty
