Well............ there arent many multiplayer maps u can do this but in the main canyon in AOTCR You can dive bomb by flying real high letting off the gas and when u get close enough shoot a banshee bomb and it will be going so fast none of the grunts/jackals/elites wtvr can dodge it.
...Alternatively, you can just hover high above them and fire fuel rod bursts from the very ceiling and they can't hit you at all, and the AI isn't clever enough to dodge fuel rod bursts anyway.
