Hey so I'll do my best to explain a bit about us and answer this though it'll be a bit open-ended.
Firstly congratulations on being the first real living human to register an account here in about three years. I genuinely assumed this post was going to be spam about viagra or get-rich-quick schemes.
BoT is, at its heart, a group of us who went to university together, friends we've introduced to the guild, and a few others that we've picked up along the way. So most of us know each other in real life and playing WoW is basically a way to keep in touch when we live variously across the country. BoT is much more than a WoW guild and there's absolutely no appetite for disbanding it or merging it into any other guild because it means too much to me and others as an identity of who we are as a group of people and a community of friends.
We don't really have a formal leadership structure. The GM is currently held by the member of the guild who most likes sorting out the guild bank and keeping guild notes and ranks tidy because we don't really need the GM role for anything else! There are three of us who are still around from the original five who founded the guild and we each try as much as possible to do a little as we can in regards to actually taking any responsibility, making decisions, or running things! The guild mostly runs itself. We currently do raids on Thursdays and M+ on Mondays but it's pretty informal and we just go along with whatever we want to do as a group based on who shows up.
I'm personally not too interested in Heroic raiding any more nor in setting up formal alliances and raid nights and such with other guilds. I just don't have the time or inclination to do that kind of shit any more. The guild pretty much runs itself, people log in, we have fun, that suits me just fine.
But if other people do want to join your guild they are, of course, welcome to do that, and we wouldn't try to stop anyone. We barely have the numbers for raids at this stage so they don't really happen much and if people really want to do raids and want to find another guild to do them in then that's absolutely cool with me. Similarly if anyone wants to raid with you while being in BoT that's totally cool with us as well. But I don't think we'd be looking to set up anything formal.
Anyone else is welcome to pitch in with ideas etc. but that's where I stand on it.
