Quick shadow priest question

[Snowy]

For elite mobs, I always pre-shield.. no sense in not having the extra mitigation. Then my order will go much like this:

Mind Blast, SW:P, VE, Mind Flay until shield drops, then fear if in an open area, and mind blast, then mind flay as the mob comes back in. If in tight corners, then I'll mind blast/wand until I get crit (I have martyrdom), then start up with the flays again.

Usually I never am fighting in tight corners though, I always arrange it so I have room to work. Fear is a big weapon in your arsenal - it can be used offensively, not just defensively.
