Basically you can shoot again right about the time the animation has you putting the weapon in your back pocket. I didnt have much time to play with it, but ranger just got nasty again.
I went rng/war and let myself almost die and used machine xbow with bloody bolts and refilled my hp in roughly 30 seconds (boyhowdy tree crawlers+) so thats 1000hp + incoming dmg.
Annihilator is definitley something i enjoyed. Though i didt get to do a group or vw, i can see where coronach is going to be so much nicer to use over last stand in some situations.
The only downside is ammo. The unavailability of adaman makes them expensive as hell, and the alternatives keep you from shining as bright. Gandiva should be fun also, but you might as well just let the ws land on youself, because once aftermath is engaged, youre ***. Its gonna cost 3x as much to play rng... But i don't care.. Ill farm dyna once per day to pay for ammo.
