How about a map setting where both teams spawn with some already built vehicles, and it is like a deathmatch setting. There is no building nor the option to create new vehicles, and last team alive wins? Perhaps both teams get limited APCs, so once the APCs are destoried, there will be no spawning? It may be fun to have tanks try to ambush the APCs. I would be interested in this gamemode because then you have to try your best not to die, and would provide a shorter gaming experience for those that just want a quick game in between long ones.
So basically it is like conquest except dumbed down and made more annoying? It just seems useless to add since we alredy have conquest. I'm pretty sure not many would like this gamemode.
I have to agree with Cheezy, conquest isnt very popular as it is. If they added a dm mode, it should be where after a set time limit each team gets certain upgrades, like say after 10 minutes, each teams get biology stuff like regen armor and bio fuel, then after 15, they get bioweapons and such, and start getting chem stuff, then so on and so forth.
