I set mine due to muscle memory and put my DOTs in the keys I automatically use whenever starting a dungeon/trial/raid. I also keep Bane in an easily accessible spot near my other DPS options, my summon close to my Ruin II, and my Aetherflow options close at hand. I keep a macro for LB(for those rare dungeons where I'm actually allowed to use it) and a macro for rezzing should it be needed. Other than that, the other places I set for what I deem fits the situation. Not the best SMN I admit, but I'm not the worst.
