@Vivejun, that's what Crystal Tower is for. I like that they've set the bar at least somewhat high for the Binding Coil section of the story. Give us something to work towards and of course it will eventually get echo buff and minor mechanics tweeks once the next section of coil is out so people can catch up. The problem I see with the current setup is they release each tier of coil before each tier of CT so until 2.3 there isn't really any relevant casual raid content.
