Ian, i like your idea about 2v2v2, 1v1v1 is just boring, if we could add some more slots for game we could make 3v3v3..
as i sugguested b4 (and noone noticed) Add 149 Sector map, to base mode.
and another idea i thought of: Defencive base, offencive base.
So, Defencive base will have A wall, defending the base, with all players/ merces inside, only that side of base will can go in/out this wall.
So the offencive will have same def (as player) to themselfs, but more attack and they will have more lives.
So while they attack the wall, attempting to reach the base, the defencive side will kill them as they attack.
so this is basically Player Vs Base mode (yeah i know it sounds kinda dub, but think about it. it could be fun!)
