Well I am lvl 15 atm, and at this stage and the previous levels domination is the easiest, you can camp and let a few teammates capture, and right before the base is captured, move in and u get easy +15.
In my opinion Dominaition sucks in BOG, cz UAV and choppers are really pain in the ass, but shooting down the chopper with RPG can give u +250 so its some advantage =] .
