The whole breakdown of this game was really thought out.
-Guild Cities with AI defenders
-Guild Forts *Again with AI Defenders*
-Roles within a guild that mean something unlike WoW
-I actually like the class system, unfortunately I haven't heard about "re-specs" yet
-Actual Siege Combat. Unlike WoW's old promises of Siege Warfare
-etc, etc.
It has RTS elements along with the MMO aspect of "Do anything you want."
Better not be disappointing.
