Notable Boss-Fight Event Announcer

[Moxie]

While running ZA earlier, a mage kept announcing things in /say such as "Debuff X is up on Player Y. Dispel it!" and "Water Totem down! Move the boss out of the green circle!" I asked her which mod it was and she had no idea, as she's using DBM and we're both sure that that doesn't announce such things.

Anyone have any ideas as to what mod it may be? Any of the other big (and not so big) boss mods that I've looked at don't seem to be quite so streamlined or handy. I'm very curious.
