Alright, so they didn't exploit the ID algorithm on purpose then. Fair enough. You can dissolve a guild and start from fresh. if you want, of course.Project Phoenix are the guild that rebuilt from No Pay Diamonds, they didn’t plan on switching to a higher guild ID- it was a founder - maybe after too many bottles of pop that deleted it one night - the other guild mates woke up to find themselves out of a guild, and the guild not existing anymore... but they started again from a stronger point than most guilds starting out in that they already had a great team together built up over years - and they were mad enough to put lots effort into building a new guild. Also many players from different guilds jumped in to help them take land in GVG and donate to treasury to help them raise their level again as they felt bad for them, including me, lol.
So PP now find themselves with a high guild ID, and because of the reasons above are a lot stronger than new guilds starting out in the more usual way.
They created a second guild, Project Phoenix 2 which has a very similar guild ID and, without understanding or intent, have created the ideal way to exploit farming in GBG.
You could do it on purpose though and get a higher ID in one or more new guilds and exploit GBG farming. You'd have to speed progress the guild though with strong members, who can push it fast to high levels and donate to treasury. If you don't, you'd just be another new, weak, low level guild with shortage of goods and copper league in GBG.
