Basically, if you want ot get more popular, it has to appeal to the pubbers. Sadly, that often means leaving out some of the maps that are very well designed, but just not well recieved by said pubbers. The conquest map Shuhia Taiba comes to mind that not many people like because of it's size. However, with teamwork it is great when you have Tansports shuttling troops around, gunships giving them cover, and armor fighting it out in the open spaces. But, you never get that coordination in a pub server and so that map is never played.
I understand that the developers here want to have all, or at least most of the maps played so everyone gets a taste of the entire thing. I don't blame them as there has obviously been a great deal of work go into them. It is a fantastic mod. However, the way it is going to grow is by the server owners giving the pubbers a reason to come back. If that means all the maps in whatever rotation they can think of, or 3-4 maps, or even just 1 or 2 maps, then great. The more players that we can get to try it and that find they had a good time, the more they will return and this thing will grow. However, if a player downloads and installs the mod, only to jump into a boring map, they might not ever come back.
Congratulations on putting this whole mod together, we are having a great time with it.
