As you may or may not know once you reach level 70 and max out your aa's you can only "save" 30 aa points towards the next expansion. However if go into "shroud form" before you reach 30 saved aa's you will continue to build up aa's until you come out of shroud form. The key is to not come out of shroud form until you are ready to be done, since once you do you will not be able to go back to build more. You will get a system message that you can not gain any more aa experience until you spend what is saved. The Task macro worked great for me !!
