It also eliminates any possibility of having some people slow to react to the debuff. It will hurt if you stack and someone doesn't move.
Just make sure you go into the Blood Rage with Fortifying Brew, Dampen Harm, Zen Meditation and Guard ready and you should have no issues. For going into Bloodrage with no stacks, make sure that you're taunting at about 1 minute to Bloodrage, and your co-tank taunts at ~30 seconds to Bloodrage and your stacks will reset in time. If you mess up and still have some stacks at the start, Zen Meditation will let you survive with any number of stacks.
If you swap at 12 stacks exactly, the tank who starts will have stacks during Blood rage. If you swap a little later, the tank who starts will have no stacks for Blood rage. So it'll be something like this:
Offtank: 12
BR Tank: 12
Offtank: 12
BR Tank: 12
Offtank: 12
Blood Rage
Or you can do something like this so both tanks get vengeance early:
Offtank: 4
BR Tank: 14
Offtank: 14
BR Tank: 14
Offtank: 14
Blood Rage
