AFAIK, pve only zone is up to 25, after that, all other zones are pvp, then there is also the abyss and siege area (Dreidgon? spelling). I think the game is focus more on group/raid pvp rather than arena pvp like WoW. All in all, I hope the game keep me interested for 3 months, everything after that are bonus.
About gameguard, I haven't have any problems with it yet game play wise but I am happy they kill it. At least it showed they listen to the gamer and 1 less potential headache for me to worry about. Now, I need to find a gameguard removal tool lol.
