"We consider communities to be an integral part of MMORPGs and we consider each and every single player to be important to us regardless of whether or not they pay for the game. We would also like to offer our sincerest apologies for changing to a Founder’s Server after announcing an Open Beta without sufficient explanation.
We would like to find a way to make amends for announcing a news that let many players down who had been waiting for an Open Beta."
This was from one of their announcements. Notice how they explain they announced it, but changed to founder server. Then they mention players are let down because there is no longer open beta.
This means IMC doesnt even consider it open beta, so why should you? Game is released.
IMO they never should have skipped the beta or at least stuck with the 3 month early access plan.
