Yeah, I think biggest change(besides defiance mechanics) is now you really should be trying to keep Storms Path up. I haven't got the hang of it yet really. Before I always tried to keep Maim/Storm's Eye up and tried to use my enmity combo as often as possible. A bit more to it now trying to keep another buff up. I do think now, if main tanking at least, Storms Path is more important to keep up. I am almost thinking about taking Storms eye out when I am tanking. It's just hard to keep both up plus doing Butchers Block combo enough.
