Sounds like the focusing is getting messed up.

Try this -- pseudocode, mind you, I'm at worx

Character 1:

/focus Character1 [target=focus,exists,nodead] // this will set the target of your other characters to focus on Character 1, if that character is alive and is near Characters 2-4

/focus Character2 [target=focus,exists,nodead] // ** note: I want to say there's a stop-gap between focusing characters 1 and 2, but I'm not at my pc right now.



Once you have the character focusing setup, copy and paste the macro to your other characters. Each of them should have the exact same macro (creates a leaderless setup without all of the hassle, because if Character1 is dead, just swap over to Character 2 - all of your characters will follow and assist character 2, do this until char 2 is dead... go to char 3, etc.)

2nd macro:

/follow focus (do this on all of your chracters) . ...



STOP! Now hit macro 1, followed by macro 2.... Did all of your characters start following the main character? If yes, then proceed. If no, then one of your characters aren't getting the correct focus.

3rd macro:

/assist focus



... That should be it.
