Yeah, you seem to have the right idea. Here's what I posted in another forum about advice on tanking:

Provoke does not establish threat. It's an emergency skill that puts you at the top of the mob's threat list for a VERY short window of time. It's only purpose is to stop a mob from getting to the healer once you've lost aggro on it. It's useless as a way to accumulate threat. Here's a good protocol for a 3 mob pull:

-Shield Toss main target
-Flash
-Savage blade combo main target
-Flash (the blind debuff will have come off by the time you use Savage blade, allowing you to use it again)
-Blade of Halone secondary target
-Savage blade combo tertiary target
-Flash
-Blade of Halone main target


Also, many tanks think they can spam Flash for group threat. You cannot. While the Blind debuff is up from Flash, another use of Flash will have no effect. You need to wait until the Blind debuff is gone before Flash will apply enmity again. That's why you weave it in with your Enmity combo (it doesn't reset the combo... you can continue to Blade of Halcyon even after using it after Savage Blade). That, and Flash only works 3 times on a target before not having effect.

Not that you need this advice necessarily, but it's good information to have.
