ok.. those are some odd macros. try these:

set focus macro (you should have 1 per character so you can switch.. using joe as the character's name)

--

/focus joe



follow macro:
--
/follow focus

offensive spell macro:
--
/cast [target=focustarget] lightning bolt

healing spell to heal the character currently getting pounded:
--
/cast [target=focustargettarget] heal

those are the ones i use mostly. works every time. no messing around with assist. assist works fine prior to 20.. but after that, target+focus is where it is (unless someone has a better solution)

let me know how that goes,
