You miss my point, so I'll be very direct.So let me ask a question - if Turbine opened up a new server called VIP, but let anyone (VIP, Premium, or F2P) play on it, what do you think would happen?
I'm betting that we'd see a flood of complaints demanding that Turbine kick off the Premium and F2P players. Names are very important, even if they have little substance.
Whatever name you call it, the name that involves the $15 a month payment will ALWAYS be "top dog" and those users will always expect more.
