Boss damage or ignore PDR nebulite?

Also, I just want to quickly point out that any crit damage bonuses weigh heavily on your crit chance. Is Asura 100% crit, or do you have a crit rate nearing 90%-ish? A 6% IgnorePDR from a Pirate set will give you a comparable bonus at 120%PDR and above (starting at 2% increase in DPS compared to no-set) to Hayato's min crit dmg bonus. But with the Kanna bonus, those 2 Sengoku cards give you in the order of 3.1% DPS increase, which is only matched by the Pirate set at 150%PDR and above.

tl;dr use the pirate set only if you're killing CPB or something like that, with more than 150%PDR and above.
