Given the fact that you have mixed arms in this game like vtols, aeros and even battlesuits, I don't see jumpsniping as a viable option so far. Sure you can usually find a spot and take a couple shots from it, but unlike mw4 the maps here are huge, and you can't just squat in a hole or behind a building for too long without the enemy simple out flanking you, or just moving to a new location.
