Healer should not dps in the dungeons?

I can't believe this is actually a thing. Getting punished for playing your job the correct way? I hope you don't suddenly stop playing the right way because of this experience.

I suspect the other 3 people may have been together and wanted to get someone else in for a win, and wanted a flimsy excuse to make it seem "legit". Either that or they are some of the most horrible people on earth. Either seems likely.
