You'll want to use Shatter Armor second after coming out of hide and as often as it comes up after that. Other than that it's really up to your recharge rate on what your attack chain is, Bane wise. For the Widow I only just recently got mine to 50 with IOs and have yet to find a decent attack chain, so i'm worthless to you in that department. If you decide to go huntsman I recommend the wide area immob, venom grenade, frag grenade and heavy burst combo.
Getting tired of my fort was wondering what is the best attack chain for nw's for single targets?
I keep finding these long attack strings that doesnt help when trying to plan a build.
Asking the same for a bane. Is it bash, pul, shatter and shatter armor when its up?
