Are new factions needed?

I'm all for new factions! It's always interesting to read other people's ideas (or share my own creative thoughts ;) ), imagine how it could be implemented in the game, and even try to create a mod... (even though I don't know how to do it :D). But! It should be a proper, full-fledged faction, worthy of being in the game. Harmonious, well-thought-out, balanced (at least in general), making a good impression, and, most importantly, truly ORIGINAL! It's always a pleasure to discuss such factions and help in their creation (at least theoretically).
