I noticed a lot of people using focus in their macros, and I was wondering what benefit it provides. I'm sure there's a reason. I'm still new to multiboxing, so I haven't fully set up my characters. Here's the type of macros I'm using so far.

Code:
Follow macro:
/follow Tehtsara

Nuke macro:
/assist Tehtsara
/cast Lightning Bolt
They work pretty well for me, although I know my macros will get much more complicated as I go along. I'm definitely planning to use castsequence macros for my totems for example. Any input on reasons I should look into using /focus?
