In that order. you never really want to go pain then vamp touch if you know you can get the touch cast off because of how cast time vs the GCD works. Just in case you're not aware you can queue up shadow word pain while casting vamp touch and get both of them off at the same time. Now if the I don't think I can get a full 3 seconds free cast before the target reaches me. I go with Vamp touch, pain and wait for DI proc or a chance to free cast.
