I’m not the one arguing. I gave you information. You’re the one ignoring it.
Then give these reasons so that we can tell you how things actually work to help you.
My guild has existed since 2007. We now have people from across many servers, including my own alts on other servers, where I can go and chat with other servers and I’m still in my guild, we still get recruits cross server and we’re also cross faction.
What exactly can you not do that is so detrimental to move your guild?
