Its incredibly annoying that you cant play online. Half the fun in these games is co-op, writing messages, seeing others. They really lose some of the charm when they go offline.
Uuuuh, say what now? Horrible? That's just lying. While I do agree that the first DLC, Ashes of Ariandel, is short and maybe not in a too interesting world, it does have one of the best bosses in the game. And the The Ringed City DLC is one of the greatest souls' DLC's of all time.
