solo wise, maxing out slow II and paralyze II is better since our 210evasion skill/200parry skill + Blind II is still nothing compared to an EM mob's accuracy :p
Slow II is best capped because of its static detrimental effect throughout its duration, while paralyze completely nullifies an attack randomly. My policy is always Speed > attack turn > evasion. Delaying the mob's turns compliment the NIN's haste gear more so than dodging hits, because that's what parry is for as a faulty back up. As for PLD, reduced speed means slower damage dealt to tank per second, and they have Block + Parry to complement their so-so evasion.
For HNM, God, and other forms of NM, this is the best blind you can get so its best to have two RDMs specialize in 3 of the Tier II/III debuffs. Because of the natural element of each spells, its best to max out Convert Recast and put as many points into Earth > Ice > Wind(Gravity)Accuracy to reduce resistance since Slow II and Paralyze II costs hefty amount of MP and at times gravity will be needed for kiting.
