The macros iceorbz posted are for a static *cleanse a friend* with the ability to switch friends when a target is dead, So by default with the entire team alive, toona will only cleanse toonb, toonb will only cleanse toonc and so on. If toonb dies, toona will attempt to cleanse toonc instead (until toonc dies)

The problem with this type of setup is that only 4/5 team members are cleansed and there is no redundency to deal with a cleanser being trapped in a GCD or CCd himself when you hit the cleanse button

Not to simply parrot Kromtors, but the big advantage of using a 5 button cleanse setup like he uses is that with 4 cleansers when you are virtually guarenteed to cleanse a CCd target immediatly on the first button press everytime
