I still don't follow. I get that Stabs become less effective but those don't really work well with Jump Back anyways. Most often it's comboed with Step 2 attacks like Nimble Strike, which Smoke Bomb has no effect on. Warriors need to get into melee attack position regardless of whether or not they have line of sight.
Yes. If they have nimble strike then it's insignificant but it isn't always the case. My point didn't cover vibrant pain so I am sorry for that. I'll think over it and edit it later. I don't find many opponents with Jump Back in the <1500 range.
That got me thinking... What if we attached Soothing Darkness to a Jump Back owner and we used range 2 attacks?
Tried that with Heavy Armor and Cone Of Cold. Soothing Darkness is more controllable so it's worth a shot.
