The problem with para blows, nerve strikes, etc. is people who run box scripts. They break your para so fast that those specials are a waste of mana. THEN you have to wait another 10 seconds to try again!
I've heard about ninja/bushido dexers lately. Not sure exactly what template but a Nervestrike / Deathstrike could get a lil nasty w/ ninja stars/darts in the mix.
