on a side note, here's my cast rotation for instances (i'm bored, my realm is down =/):

/target focustarget
/castsequence [nochanneling] reset=target, vampiric embrace, vampiric touch, shadow word: pain, mind blast, mind flay, mind flay, mind blast, mind flay, mind flay

I have 1 pt in improved mind blast so that the cooldown of mind blast drops to 7.5 seconds, low enough to allow a MB+flay+flay rotation.

anyone else created a complete rotation like this so they only have to spam 1 button still? ^_^

EDIT: btw the nochanneling modifier works like a champ now! I *was* pulling less than 1/2 the dps of my ele shamans, now im up to more like 3/4 their damag
