Being the raid leader of my guild, I have been using Acheron to track the death of people in a group forever. Since cataclysm came out, the addon has been getting more and more broken every patch. It is now unusable IMO.
I have been looking for another addon that does somewhat the same job. Track death, have a clear overview of the last few seconds of a player before they died.
I did try addon such as recount and Skada but the report are very hard to browse thru and it takes much more time to use. I also tried Fatality but its annoying as hell since it spams all the time in chat and it also just give you the KB and not what happend before (heals, standing stuff).
If anyone have an addon they know, i would greatly appreciate it.
This could be a replacement for you, if the "hints" above didn't work out for you: Death Note. Sadly I can't give you a link (yet!), so just check out Curse for it.
