G'morning Gripen and welcome to the forums!

you will need to put your clones on /follow and put your movement keys on a 'do-not-pass' list. to do this, make a follow macro on all your clones:
ie:

macro: follow
--
/follow focus

then make a set focus macro on each clone... for each clone (if you are 5 boxing, that would be 5 macros per clone)

macro: focus-jim
--
/focus jim

macro: focus-sam
--
/focus sam

macro: focus-joe
--
/focus joe

macro: focus-bob
--
/focus bob

macro: focus-sue
--
/focus sue

then put each set focus macro on the same key for each clone.
when you hit that key.. it will tell your clones to focus on that clone.
then you hit your follow macro, and your clones will follow their focus...


this would be the start of the more advanced macro setup.. then the simple /follow and /assist
