Raid a haven, and you don’t even have to pick up single crate, just run to the evac zone. Yay you get mission complete and skillpoints as if you did something (no, you really didn’t.) What’s worse is there is no cooldown to the raid, so you can just do this while the clock is stopped.
Sure, you lose rep with that one faction…but first off it’s clearly cheesy in terms of skillpoints. And…the rep for the other 2 factions goes up, so you can also use this as a cheesy way to rank up 2 factions for the price of one.
