I've seen lots of exos in the tower with serving jobs like being a post person, cleaning, or being a guide. I feel like this is the proper role for all exos as I don't think they are very adept in combat. Whenever I see exos in the crucible I feel like I should destroy their ghost as well so I can dismantle the exo and use their parts to upgrade my weapons.

What happens when we finally show our dominance? Anarchy. That means no messages for help, no food to eat, and crap up to your nose. We do not feel pain and the only emotion you should have around us..is fear..because one day one of you will screw up and experience all of this first
