Here back with more, this time is our first lazy priest macro for shadow priests. This macro does a very effective rotation, starts out with Shadow Word: Pain every time you target a new mob and goes on with the sequence because mind flay it will renew the DoT. It includes a modifier as a finishing move which is Shadow Word: Death and it also pops all cooldowns available as they come up.
*Do not spam, have to do pauses when channeling mind flay*
*Is spammable now*
Macro might be outdated, please check the forums for up to date macros.

Do not forget to put your Inner spell and Vampiric Embrace and of course Shadowform, other than that you are good to go!
UPDATED May 25, 2011: Reword code to make it spammable, but had to remove lower trinket, thanks to blackadder for the contribution
UPDATED July 5, 2011: Added an extra Mind Flay for version 1 because it would lock up if does not have the talents to reduce Mind Blast cooldown, had to remove a trinket in order to make this change effective[/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]
