Disabling Baghnakhs inflict Paralyze, Poison, and 2 more enfeebles I can't remember atm, in NMs I see Poison and Paralyze in the NM, so I don't think it's very hard to land Paralyze and Poison, I would say 1 in 10 hits (this for Pugilist is nothing since Flurry is 3 hits... lol).
And I have a pair of +1 Disabling, it's attack gets higher than NQ Peiste Cesti, so yah, I think it's more useful using the disablings, more useful in NMs in my opinion~ ^_^
