Quote:1 : a party or group (as within a government) that is often contentious or self-seeking : clique
2 : party spirit especially when marked by dissension
Definition #1 implies there is some sort of organization or group striving for some sort of goal. Definition #2 is entirely political. Both of these imply leadership and structure. What is structured about a Mercenary working for himself trying to make a buck? Also, what is the official faction that can dictate to independent mercenaries/freelancers/generic pirates what to do as you clearly want?
Are doctors in a faction? What about pharmacists or nurses? They're all registered with an organization that regulates them. Would you consider them part of a faction?
If Discovery has it's own definition of faction I'll acknowledge that, but as for the standard definition in the English language, me equipping a generic pirate ID doesn't make me part of a faction. If you can't comprehend that in regular English, then I'm pulling the handle on my Russian NeverFail ejection seat.
