The loot rolling could get tricky.

In wow a window would pop up and you could click to roll.

In Huxley since it's FPS i'm guessing they would have something along the lines of
1: Need
2: Greed
3: Pass

But if your in the middle of combat gatting something up and you hit 1 to switch weps and roll need on an item, taking it from someone else, problems could arise.
