Basic macro that will work when master is dead?

[MiRai]

Are you saying the way you do it is you hit one button that gets all slaves targetting the master's target and then use regular ability keybinds or macros that a single-character player would use?

The way I do it is use ISBoxer which let's me target the lead character regardless of who I switch to.

The way you can do it is make a separate assist macro and then press that button when you want to assist to keep your other macros free of having a hardcoded assist (so they work just fine when you play that character manually).
