To start things off, macros confuse me, they always have and probably always will. That being said I know as a multiboxer that they are necessary so I was hoping for some help.

What is the benefit of using /focus over /assist

Im confused on what can be done with /focus that cant be done with /assist
I have read the stickies and macro guides, and im just plain confused ?(

Thanks in advance
