I have a nice little Berserk macro to let the healers know I'm shortly going to be Pacified. Doesn't always encourage them to clear it off me though...lol. I also macroed Holmgang for the benefit of the healers as well as so people know I'm not intentionally eating an AoE...Im stuck to the ground!. For SMN and SCH I have lines on my Virus macro to let people know I debuffed the target. It's also designed with a "target of target" so I can remain targeted on the tank for heals and still Virus the main target.
