"Narcissist" is not a slur about a group of people with a disease. The word refers to being self-centered in general, and comes from a Greek myth in which a young man (Narcissus) falls in love with his own reflection. Narcissistic Personality Disorder is not a "crippling disability," it's a personality disorder which can be worked around with counseling (psychotherapy) and effort. Calling it a "crippling disability" makes it seem insurmountable and that is not a healthy attitude. Also it isn't caused by having been abused as a child. In fact, there's no consensus about what causes it (or any other personality disorder). It's believed to be a complex interaction between biological and social factors, but there is no specific formula for causing it.
Please educate yourself about these issues before criticizing others. The misinformation you're spreading does more to harm those affected by mental illness than to help them. If you're really interested in helping and defending them, this is not the way.
It took me less than an hour as well. I did the Steel Path version, and got one main Dante bp and more than enough pity points to buy the rest. In fact, I got pretty far into building all of the new stuff. I bought the hand cannon bp and two or three of the pieces of the melee as well. It's really quite painless, comparatively.
