Now that I've actually had a chance to try this addon, I can tell you, i've been looking for this exact functionality for months! GREAT MOD! Oddly, I probably won't use the buff thing, just the CC breaker -- I wanna know who's messing with the shackles and frost traps, and hopefully a little raid-party posting will make them smarten up (yes, it's harsh, but some people need to learn).
However, I noticed that it doesn't seem to tell you when someone breaks CC from melee. When the rogue melee broke a seduction, nothing was posted. When the tank melee broke a seduction, nothing was posted. But when the tank shot the seduction, a post was done. This really does go back to Part B of my original post and Halthron's request of filtering only certain players, but even more than that, *not* filtering when the other players do melee to break CC. I've had a few bad hunters sick their pets or take a melee swing at shackles lately, and I need to be able to catch those.
Other than that, *GREAT* mod. This is my new top addon recommendation for any raid leaders who need to restore order!
