Both have a nice self-heal, but that's the only similarity.
/WP is a good "set it and forget it" set. Other than hitting your heal here and there, it's got a little bit of everything, defense AND resistance (which a bunch of other secondaries cannot do), and that includes Psi damage. Plus you can cap your HP early on with /WP.
/Nin is awesome for feeling like a ninja. Lots more to do with mitigation. Caltrops, Blinding Powder, and Smoke bomb are all good for keeping mobs out of your face (well, smoke bomb, not so much)
But you are choosing between the two best sets for stalker secondaries, can't go wrong either way.
Hey guys new to stalkers and love the animation for dual blades on this side. Can you guys give me some input on what you feel would better to pair with dual blades, nin or wp. I plan to pve 99% of the time. I also would be love if some one could take me threw a stalker boot camp, to learn the play style. I am on Victory server.
Thanks
