I did some testing in SSS on A12S. I can get the dummy down to 5% with no macros. Consistently had 15-20% more health with macros when time ran out. Additionally, I could tell I was attacking slower because I had no TP problems with macros. For monk, if you can wail on a target without ever having to stop for mechanics, you can run in to TP problems. I never came close running out of TP.
