Yup, staggering tremor totems is quite effective. You'll notice how quickly I pop out of fear in the video. You make a good point about the EMCL. I am probably going to change the way I use it. Maybe LB -> NS EMCL -> Shock? I doubt anything could survive that without an Iceblock or Divine Shield.

I don't think a mod would solve the targeting issue, as it wouldn't be any faster than /assist, but it sounds mighty handy for checking out the opposing team. I believe the Priest I was with used it. He kept telling me their gear and arena rating on vent.
You are definitely right, I need to be more efficient with my targeting.
