More bases just delays the inevitable because with a growing community, I'm fairly sure we'll have more big name gangs in the future that just "home base" the new bases. It'll be like Neo base where it was mainly a bunch of newbie startup gangs until gangs like Guk and Kin came around to dominate it.
I kind of like the idea of finishing the gang points system that way rewards done have to strictly rely on basing. Slowly rewarding PKs and gang spars would be good for small gangs that can't dominate a base for hours on end.
