You dont need a Face Target macro, just Interact with Target. You can two-step it I believe as well so have first step Interact with Target to have them face the mob and 2nd step takes a step back.

I think your problem is a gear problem, once your dps is doing 20k+ you can get through them. I run those dungeons on my team and seldom wipe at all anymore, they are all around 383+ iLevel.
