I very much doubt there are any differences lol. It was expected that there would be a bunch of no effort servers put up in the first few months of release, this ones just the least effort so quickest off the mark.Why would people play a high rate that's probably had no balancing changes made from Zircon, hell probably no changes at all apart from your system message and exp set to 500%? No new areas so people will blow through all the content in 30mins?
Maybe let people know whats different from Zircon other than insane experience? I'm gonna say not much.
