Not sure what ship are people are talking about. Personally I like standing on the boxes because it feels cool and more realistic for a sniper than stacking up with melee classes. But I don't mind doing the fight either way. Since most of the people are way overgeard for the fight by now, it doesn't matter which way you do it.
straight off the elevator you are looking at the back end of a car/ship/thing...you can get on top of that one. thats what we are talking about.
