I've conditioned myself as a healer not to be annoyed by it as I'm actively watching buffs/debuffs and don't need a reminder. But I realize all healers may not be as observant and watching for it. I try to get berserk off as long as I'm not handling a mechanic, doing needed healing or spreading dots. It's worth getting off the tank if I'm in broil spam. I'm never standing around doing nothing but in that case a healer better get it off the tank.
