I searched the forums but I couldn't find anything about it, only something about not wanting it in the start (because they wanted to have the "launch"-feel) but it's been a while now.
Anyway when I started they said they didn't want a PvE server because this is how they wanted it and if anyone wanted something else they were free to go somewhere else or something. So I had no choice but to start a PvP server, but now that a PvE server is available, it feels a bit silly that I have to put 7 more days played to get to level 60 there.
Also people keep spamming that the PvP server is overpopulated so why not?
