Just soloed these as a 74 Nin, sneaked up and popped them, provoked one of them from a safe distance and starting getting into him. Kept up paralysis, blind and slow (all 3 saved my backside), had an eva build to go into but still had pretty decent accuracy when it wasn't blinded.
The other one depopped when the one i was fighting was down to about 1/4 of his hp left. All in all, a few slip ups but still killed it off.
