For the sake of not letting the hype blind me, I haven't spent much time studying Age of Conan in advance. I'd rather play the beta, starting tomorrow hopefully, and see for myself. But while I don't read the AoC official site, I do read blogs, so I can't help but get some information from there. The best source I've found up to now for Age of Conan commentary is Keen and Graev's Blog. While I had to sign an NDA to get into the open beta, Keen says the NDA was dropped for participants in an earlier AoC event, which I find confusing, and somewhat ironic, given that Keen once chided me for breaking an NDA a few hours early. So he has not only comments on various AoC feature announcements, but also first-hand experience tales directly from the game. Anyway, in his latest post he is talking about AoC's battlekeep vulnerability system. In other games in which guilds can conquer keeps, like DAoC, those keeps often change hand at 3 am, when the owning guild is sleeping and the attackers organized an early bird raid.
