Blizzard has said it they plan on fixing Ebon Plague. Whining about it won't get it fixed any faster.
Is anyone else upset over Ghostcrawler's reasoning behind Ebon Plaguebringer still not being fixed?
However, as I said the last time this question was asked, our priority right now is making sure more DKs spec Frost or Blood, not how to reward groups that bring multiple Unholy DKs. We do recognize it is annoying though and we'll get it fixed.
One of the biggest banes to Unholy spec DKs is another Unholy DK. It seems that this isn't being fixed because Unholy is popular amongst DKs, and they want DKs to use the other specs more. I don't really see why they consider having multiple U DKs a "reward". There isn't any extra utility that they provide, other than AMZs, I suppose.
Looking at these forums, you can see that every spec is very much talked about and used. Do you think Unholy is more popular in game because it has more fun mechanics and is suitable in more variety of situations?
