yeah, joining a guild and then having others join is just a way of networking better. That way, when ur in a pinch and u need 1 or 2 more ppl to help you grind/quest, you can just use guild chat: “/g [message]” and throw something together. Plus, your guild master can assign all sorts of titles to members (ie: vice guild master, general, knight, craftsman, etc.)
the guild update i havn’t seen used yet. It probably works like a message board that the guild master can use so that all guild members see the message when they open their guild menu.
