It was mentioned in the post below that there are different guild guardian statues for different mastery levels:
I just checked, and it’s true! Increasing mastery makes the statues more ornate. Unfortunately, I can’t see all the different options. (I’m on iOS, which limits my ability to go data diving.) Can someone do me a favor and show me all the different statues I haven’t been paying attention to for the last six months?
Very cool. Thanks for putting these up so quickly. They seem like a labor of love to me; it’s not possible for anyone except Steam players to compare side-by-side statues to see how they change, and without that the upgrades happen so rarely you could miss them completely.
