Being a Xeno means that you have plenty of enemies and no other faction as a friend.
Added to this there is the geographical restriction, the restriction on not being able to pirate, the restriction of no transports (=no money), the restriction on no cap ships not even gunboats, the lack of powerful friends and the lack of ANY shield busting weapons, the list goes on and on.
My guess is most of us who have a Xeno character have chosen to be Xenos because of a desire to be non-conformist in one way or another. Therefore there is no desire for a military style set of ranks, with the associated duty to follow orders.
So is a faction needed? Possibly not. However a faction gives you a sense of belonging to something. Xenos have a lonely path to lead. Maybe some identifiable friends might be a good thing. One thing for certain is that it is no army. Any Xeno faction would rightly will be a weak faction.
Also it need to be role-played with some sensitivity. The location of any Xeno faction means it would need to deal with relatively new characters (levels 30 45) that may be new to Discovery. Becoming a true terror just outside the doors of NY would potentially be very damaging. However a faction of Xenos might be better equipped to do this RP correctly rather than a group of individual terrorists.
So I am asking whether the community thinks a Xeno faction would be a good thing.
