To me this whole thing comes down to whether or not NF is worth it. From what I am reading here and everywhere else that has theorycrafted this I don't see how anyone could say that it is. The numbers Theloras has provided shows that a single ret paladin wielding NF on a pure tank and spank fight can, when adding the dps contribution of the NF buff, do dps on par with good dps. But in every other fight, uptime goes down, and he starts to fall to the bottom of the damage meters.
Adding additional NF wingers has diminishing returns. So adding a hunter, who will deal next to no damage, for an additional 20% uptime, will not be able to make up for losing a real dps. Adding a third is even worse.
Further more, there are many fights where NF is either useless, or will not be able to provide even close to the uptime that it can on fights like Patchwerk.
So if you are trying to min/max, why would you bring 2 bad dps that can sometimes provide a buff to magic dps that will get you the same raid dps as you would with 2 good dps? Especially when they won't even be able to do that on every fight.
Now, if you have a ret friend that refuses to heal and you just want to raid with him, sure. Letting him swing NF will probably make him feel better about his bad dps. But pretending that NF is actually good for anyone other than the OTs is laughable at best.
lol but it is directed at your logic
PS a Ret Paladin 8/8 Tier 1 on fights like Thaddius and Loatheb make the encounters simply a cake walk for a raid to beat:
