I play assault alot, i have unlocked double c4 also. But, in the light of the vehicles having their resource cost increased by a lot, making it VERY HARD to spawn mbt or other vehicles BACK TO BACK ( in case your tank gets destroyed immediately, as it usually happens), i think the cost of the C4 brick should be doubled. I use c4 a lot, don't get me wrong, i fly above and drop them, i got a 27 kill streak once, i am happy with it. But,it is not balanced with the increased resource cost for maxes or any other vehicles. Before you jump at my jugular, think a bit , how much c4 it is needed to eliminate a tank or a max, how much a c4 brick costs , how many times can be acquired back to back via resupply from sunderers, and how much a vehicle cost, and how many times we will be able to re spawn such vehicles, back to back. I like an infantry based game , but frankly, there are way more better games that focus on infantry only fights out there, so balance both sides. 250 points for a brick should feel more in line with the new incoming GUO11 "improvements".
