Maybe my new macro`s are just wrong.

I currently use, 2 pc`s for 4 shamans.

I have 4 hotkeys that are bind to a macro:

/Focus toonname

The 4 hotkeys change my focus.

Then I have the 2 macro`s:
/Follow focus
/Assist focus

So far it seems messedup, I have to bash the assist button a few times before my toons assist, follow allways works instantly but assist is just crap. Now my targetting takes forever and when I try to assist on a friendly target I have to hit the button a few times and toons go on different targets, like the new one and the one before.
