I keep seeing different BP's listed as clickies but I'm not sure if when it was written those were the current expansion war BP... This is specifically for Warriors on Live.
Highwater Breastplate of Havok
Warrior Conflagrant BP
Is it like other classes, where you keep anguish chest (the classes that it makes sense) and your most current chest piece (as the previous expansion chest is just a worse version of the current chest...)?
