Along the same lines, as I've seen some Guardian tanks do this, do
NOT use Savage Defense immediately once you pick up the boss or on the pull if you have no Vengeance! You need that baseline Vengeance from getting hit once to ensure you keep threat, and getting hit once should not mean the end of the world by any means (especially if withholding SD still results in a few dodges immediately, rage used for something else).
From my personal experience, absolutely zero threat issues thus far. The irony with Guardian tanks is that the better we are with our 'active mitigation' cooldown usage (i.e., SD), the worse our Vengeance will be compared to other tanks. So naturally, while we're dodging attacks left and right, any other tank taking the hit and mitigating the damage is gaining more Vengeance. However, from my personal experience again, it would take my tanking partner being destroyed into the ground before threat became an issue. Just ensure you're communicating or anticipating tanking swaps since landing a huge threat ability at such an occasion is generally not appreciated by any tank.
