I quit PvE in 3.2 when Trial of the Fail came out, so I am not sure. Is Ragnaros in Firelands immune to fire? If he isn't I personally think that is... ugh, although I can understand why (So no need to elaborate on class PvE balance), I had no problem at all with making any other boss non-immune, but Rag is pure fire and it seems a bit silly (For lack of a better term), they could of at least given him some debuff Cenarius (Or one of the others) cast on him making him vulnerable to it (That was merely cosmetic for lore reasons).
