Easy. Don't play Fps online
I do it offline too. I love making my little brother rage on that da valhalla stage.
Grab da banshee and a sniper rifle both positioned at near reach for your own convenience.
Fly fly fly up up up up high into the top of that structure.
And snipe to your heart's content as they weep for each mysterious death they suffer. This makes you incredibly leet as you dodge rockets and lasers and scorpion tank shots and banshee fuel shots and nades as you snipe them back because you're that badass.
Even works well online too, difficulty is notched higher due to simply the virtue of having more than one opponent gunning for you and envious stormtroopers that can't the broadside of the barn attempt to aim at you to take the sniper for themselves.
