Wow, this is so cool, Daniel!

How do you go about ranking each guild? Is it based off of levels/number of members? Or is it based off stats?

Again, this is really cool and I'm not a whiz at making these sort of things. But with PL's given guild system and lack of guild activities (including both PvE and PvP), I'd find it difficult to rank each individual guild. There's no guild-point system in PL that would correlate with rankings.
