Yes and no. The Chola, moving into Zodiac, has been around for awhile. Community-wise I would say Zodiac is doing a much better job than BK, but mechanically BK seems to perform better in a fight. I think as you said, BK's leadership is struggling to maintain their own community right now. The influx of more people to help manage it might help them.
Basically, because of how alliances are structured, there is and can only ever be a 1% of people that "matter". ie - the management team. The leadership is what matters. So therefore, the concentration of leadership and their chemistry are what matters the most. It's why every alliance that exists is boring right now. There's one or two people who are too busy trying to stay alive to actually thrive. I believe there is a third way, as Arrgh aptly demonstrates, but c'est la vie.
Hopefully they can swing a best-of-both scenario because Partisan is right. Regardless of what side you're on, IQ is *boring* in its current state. They're not having fun, we're not having fun, even Fraggle is losing interest.
