When these scenarios arise a third or fourth tank usually doesn't have a 'hard' job, and if Vengenace DHs are self-sustaining and do this much DPS, you can be rest assured that they will be the first option sought, because why not?
Early in MoP in 10 man, if you could run two disc priests you essentially had the luxury of having two of the best healers, and they pretty much combined for a DPS. So what would be 2/2/6 was really like having 2/2/7 in a 10 man format. If you needed three healers the same thing was true, 2/3/5 was more like 2/3/6 because of the added DPS.
Tank and Healer DPS does matter, especially when they aren't that far off of actual DPS numbers. Really doesn't matter if it's farm mode or not, people can see the potential of a tank doing that much DPS and will try to fit it in as much as possible.
