Yes you can upgrade without resetting, but generally only new chunks will have the new stuff.I'm not really into the faction idea, I wasn't too enthusiastic about implementing it to begin with.Also I'd kinda prefer not to reset, personally. But if it'll make it easier for people to access new stuff then I understand.

Well factions work well for antigriefing anyway. That is, unless you start a city and let everyone in on it :P

iirc, there isn't many new things that need to be generated. Ocean... temple... things- are about the only thing I can think of.

Well, that and all the new terrible-looking and useless stone.
