Forming a Clan for the sake of having a new Clan isn't a good idea. BUT, if it grounded in the story and the circumstances call for it . . . yes, it can be a good thing. Personally, I thought that the pre-Revival 'superclans' (i.e., Wolf, Jade Falcon, Ghost Bear, Smoke Jaguar, Star Adder) were getting too big. Especially given the limits on Bloodnamed Warriors. I mean 60+ Clusters for a single Clan was a bit outrageous; the tension between Warriors seeking their Bloodnames and those who had them must have been enourmous. Only 500 Warriors per Clan can have a Bloodname, after all.
