There used to be a plug-in for grid that would show an icon if anyone in your group was missing one of your buffs, but it is outdated.

I'm a priest and wanted to set up a way to show if people DON'T have a stam buff (Fort, comm shout, blood pact, whatever hunters do). I know I can set it up to show if someone has them, but is there a way to group those all together and show one icon somewhere saying they don't have any of them?

Thanks n junk.
