If you really want to make a faction, I guess you should take in consideration these questions(I am not saying no to your idea):
1) Are you truly prepared to lead a faction? (Note: Decent english and sense of leadership is required)
2) You wish to expand your RP capabilities so much?
3) Why do you want to create a faction.
4) What are your expectations on your faction?

In any case, I don't see the problem in another faction in Discovery. People who tell you not to do so...well..they are trying to change your thinking by their will. Don't listen to them. I promote new factions in Discovery for the simple reason: This is an ROLEPLAY server, that does not forbid you to do Role Play with another people, to meet great players, and make a LOT of friends. Things are much funnier when doing teamwork, trust me
