No details such as balancing of "points" or anything like that has likely been told to anyone, but I'm pretty sure the core concept is to make guilds less of a tag used for a purpose and then discarded and more of what a guild actually is supposed to be. The same group of people doing activities as opposed to recruiting and kicking temporarily is likely going to be incentivized in some way, and guilds will probably be used for more than just 1k tags and guild spar tags.
