It´s really hard to find a good way, to sort all those maps.
Right now it isn´t optimal but I don´t like your idea also randomlyrcis
If you are searching for a tactic map and a players know (let´s say a player that haven´t played for 1 year KaMR) He will search for a map and won´t find it. Maybe he will look in the other sections, but rather not!
Biggest problems are maps like
"The Maze"! :
+It is a tactical map, because you can´t build any buildings there (Definition of TSK/TPR)
+It is a coop map, because you are playing with 3 other human players (Definition "cooperative gaming")
+It is a special map, because what? Well, because it has a huge scriptcode, that effects
massively at the Gameplay.
My aim/wish would be, to delete the special section at all in LATER RELEASES, if there are enough special maps. Right now these maps are special, but for sure in one year there will be a mass of scripted maps, which means they should get together with normal eco/tactic/coop maps in my opinion.
If you would search for The Maze, you would directly go to the CooP Section, "
because you are playing with 3 other human players" and it doesn´t matter if this coop map is a tactical or an eco. mission.
So in my opinion you shouldn´t make it more complicated with that submenus, but rather try to delete the special map section and put them all together to the rest of the maps, without any confusion (Is the maze now coop or special?). However like I just wrote, this will work only in later releases, when there are more scripted maps. Right now just noone would even know that there are new kind of maps and noone would play them
