This is not really a bug, it’s just something i don’t see really accurate.
Afaik, a “guild” was a coalition of professionals who shared their business activity, while the templars were an order of cleric warriors.
I know that they are commonly called “gilds” on every other online game and I’m not completely against needing a templar for creating the gild, but Imho they should be officially called “brotherhood” or “order” instead if the templar requirement is kept.
Obviously people would still call them as they do but I believe it would be a bit more immersing and fitting.
