As I said before, Ret palas are the best Nightfall users, you can keep JoW up, extra blessings (and guarantee salvation on the raid), an extra dispell and have an extra DI. And you might say "oh but you can bring an holy paladin and still have all that except the Nightfall debuff" which is true but you can have more healer diversity and bring more druids can that insta rezz and priests while still retaining all the Paladin blessings and everything that I mentioned earlier. How is that bad?
