Just a reminder, while it's great that people run the latest and greatest versions, as it helps detect problems like the ruRU one, the official versions of the addon are found on wow.curse.com and everything else is to be considered as alpha and are possibly untested.
P.S. Thanks for the log files, I'll see what I can do to get some useful warnings/bars.
Wow, you guys are quick, thanks for all the logs, I'm working on them when I can, of course I want to play too, I got Azul'Nerub done last night I think, haven't released it yet, but it's in the alpha builds on wowace.com of course. I might get some more done tonight, if not it will probably be the weekend before I can manage to get more added, but thanks for all the logs please keep them coming.
Also if you have suggestions for specific bosses that's always helpful, as I haven't always experienced the encounters myself to know what should be warned or displayed.
Littlewigs prints a message for missing bosses most of the time ;) but i think we need all heroic instances and everything above level 76 (utgarde pinnacle, oculus, cot3...)
but i dont think that matters ;) log them all and post it here, the more logs we have the better, because most of the time the bosses die to quickly.
I wouldn't say this is entiredly true, unless a heroic encounter has some aspect that isn't in the normal encounters. Any spells that are different between normal and heroic I can usually take into account as both spellids are listed on wowhead.
But yes Yoshimo is correct in that all bosses that have no warnings (save Stratholme, for some reason I forgot about that instance completely) should spew a message to chat when they are activated requesting that you log them and submit them.
