Not even. UAV is 375, CUAV is 475, and the lowest pointstreak, the RCC, is 325. That means...
RCC - Two flag caps, 4 kills, or a flag cap + a kill.
UAV - Two flag caps, 4 kills, flag cap + 2 kills.
CUAV - Two flag caps, 5 kills, flag cap + 3 kills.
Seems balanced, yo.
@ Pluvia: I guess. It depends on how they're doing the XP system as well. Search tends to give 5x TDM kill scores, so...
Alternatively, they could make XP != score, but they typically only do that during double XP sessions... If they're just using multipliers though, it shouldn't even be hard to manage. ._.
