Note, the above macro set will work on ALL your characters. You can literally swap between mains at will if you use a different set of focus macros. (The one I have listed below is an "oh crud my main died, let's pick a new one" type emergency macro.

I recommend a separate set of hotkeys for all your characters that assigns a focus to each of your team. It's a useful thing to have at your disposal. For example, I set loot to FFA and simply rotate through mains when doing the few collection quests that I want/need to do.
