The TLA command ability does the exact same thing as spiteswarm hive. They both allow saving throws of 1 to be rerolled. All out Defense adds 1 to saving throws, so the best you can do is a 2+ save with rerolls of 1 (which can only be rerolled once). Even if you were to somehow get to a +3 to saving throws, after any rend is subtracted you max out at a +1 to saving throws in the best case scenario. Unless I’m missing something, it looks like you misplayed some things. As for the issue with the Hunters, I’m guessing the issue resolved around their envoys of the ever queen ability? Rereading it now, I can see an argument against them providing the aura due to the wording. I’d suggest submitting that question for FAQ.

They do not get around anything. The three types of moves are Normal, Run, and Retreat. The ability it above says that it can be done instead of a normal move, but a normal move cannot be done while engaged. Therefore, the only option would be to retreat, which does not allow for the teleport to happen.

No, a priest can only cast one prayer they know. Invocations are just prayers a priest knows.
