In that case RoH should register at the beginning (like how they changed warrior's stun), and let RA register at the end for the oomph. We are tanks, our main tools should value function over form, right?
Indeed, the RoH animation delay is why I've always used comboed SB on tank swaps, and for picking up adds. A4N as ST I also almost always do my Fast Blade just before getting Quarantined so I start with Savage Blade -> Spirits Within -> CoS -> RA in Quarantine, never having to use RoH unless the DPS is wielding 190 with full 180+ gear.
