Idea is to show which abilities are which brawlers, enabling DBM's new GUI to basically be a encounter journal for brawlers guild.

This work is on hold however until next season because blizzard always moves bosses around and it'd be silly to do the work now when content isn't available and when it is, it'll be different.

I'd put money on this being one of 9.2.5s features.

Doesn't seem to be happening, closing until 10.x
