I hate the obnoxious "oww look at me I'll be pacified in N seconds" TONS OF NOISE macros... I'll simply ignore most. But I've did one thing for when raiding with my team(and I might use it elsewhere as well).

I have a macro:
/ac the warden's paean <6>

That way I can squeeze the ogcd without interrupting my rotation. Of course this only works if I get a simple "Berserk up!" macro. But it's just like the the flaming arrow - it means I don't need to position/search stuff and can use it as a fast ogcd.

If I could see berserk easily on wars I'd prob use it more often but it's often on spot 6+ so not visible in the party list.
