Yeah, when I'm playing with a team of six, we always have at least one person(usually 2) running support UAV/Counter UAV, with hardline. It auto resets itself after 4 kills, and if you're playing objective, or just really stomping the other team, you can usually get two people to have 3 uav's running at the same time for the advanced UAV.
I still think dropping a MOAB should end the game though, especially since kill streaks dont count towards that. If I get 25 in a row on a team, using nothing but my bullets, they should just lose by default.
