I dunno, I really can't stand tanks that do things like this. I had one that had a cleanse macro that would countdown and then request that I cleanse a poison or something off of him. Like can you not? I'm fully capable of watching that debuff/buff bar of yours and cleanse it as soon as I can. You don't see people telling dps to do this and that so why do some tanks have such insane control issues over their healers?
Was it a warrior?

Because I like berserk macros. Sometimes I have trouble noticing the pacification debuff until it's almost over anyways.

if you aren't aware, when that cd wears off they can't use weaponskills for 5 seconds. an be annoying and can be dispelled.
