If you believe camping is the only form of ground combat, why don't you go fishing with some dynamite.
Actually, I do. (Not the dynamite part.)
Doing away with double spawns will not decrease camping. It will just take a little extra time to get to the spot to camp.
GV-ing in AH is all about camping. When TT was retooled to do away with long range camp-sniping it pretty much killed TT.
Double spawns give you instant tank action. The only need to move is to find cover. If anything, they promote gv-ing.
People are always going to camp spawns. Doing away with double spawns won't get rid of campers. Look at the people who will drive to a V-base and park behind the spawn hanger.
What would be really interesting would be double spawns that span in the same place. No telling if the next guy would spawn in front or behind you.
