I installed it because IcyVeins said to. There are a lot of nice things about it, but one thing that is annoying is I cannot figure out how to make critical debuffs show up well. It seems to be largely arbitrary which debuffs get highlighted by default. On Opulence, I could not see who had Hex of Lethargy, and on Conclave I could not tell that some people had huge DoT stacks, or who had Crawling Hex (I could see that in the world by the big circle around them, but not on the raid frames).
Does anybody else use it or have a better suggestion for showing up debuffs?
