lol I ran that exact same chrono 2 hours ago!
This is one raid where the old "accept whoever hits the LFM" strategy is an impending fail every time. This raid needs either a group of random extremely well geared and skilled players or a very good party composition. Miss either and it's fail city.
We had a good group earlier actually but the lagmonster was just too much. We wouldn't even see the red dragon form and then DING DING DING DING DING half the party is dead and THEN she turns into the dragon. Nice.
