Yesterday I've thought about a little trick to (extremely slightly

) increase our dps at the beginning of a fight:
Before the pull, equip
[Idol of the Black Willow], cast a Rejuv and switch to your regular DPS idol. A free 256 additional SP at the pull...
I can't log to the game right now, but do you think it's reasonable to create a macro to do this during a fight? A macro to use while in movement?
Something like:
/showtooltip
/equip Idol of the Black Willow
/stopmacro
/cast Rejuvenation
/stopmacro
/equip Idol of the Lunar Eclipse
/cast Moonkin form (not sure here...)
PS: Sorry if this had already been discussed...
