I wouldn't want to Macro the main combos, but I have been thinking of Macro'ing Third Eye into most of my main Combos so I have a higher frequency of the 5% dmg block leading to other oGCD skills and I can clear up a hotbar space. I would like to hear anyone elses Macro ideas for Samurai, I think there are definitely some Macros we can think of that will help simplify something here or there.
