Here's a more compact form of the macro that switches focuses depending on who's dead:

/focus [target=<name>,help,nodead]; [target=<name>,help,nodead]; ... [target=<name>,help,nodead]

You can add as many [target=<name>,help,nodead] as you want; they need to be separated by semicolons. Where I have <name>, just enter the name of the character to focus on. This is a lot more compact (only 145 characters for my group of 5). It also checks for 'help', which means it should skip over mind-controlled targets properly.
