MY WAR isn't BiS because the gear set is entirely too different from my other 3 tanks, and I can't hold more than 1 Unique item in my chest. So it's stuck in full Idealized gear.
WAR is very simple, only a few things to keep in mind: always keep enough gauge to hit Upheaval on-cooldown, and if you have 8s or less on Storm's Eye, refresh it. other than that, spend your Infuriates as necessary, and whack away.
