Level 45+ Shadow Priest

[Geboran]

Ok.... so my shadow priest just recently hit level 46 and I am enjoying her more and more.

I was wondering though.... when questing and I need to "kill xx" number of mobs or whatever (similar to grinding), what spell combinations are the best to use for doing these sorts of quests?

Typically, I will open with:

Vampiric Embrace ==> Mind Blast ==> Shadow Word: Pain ==> Mind Flay

Then either do another Mind Flay followed by wanding till dead, or will put up a Power Word: Shield, Mind Flay, Mind Blast, then wand down to death for the tougher mobs.

Is this basically what I should be doing, or is there a better way of going about doing this?

Any advice / suggestions welcome. Thanks.
