So watching those two videos
Running Shot + Full Dex build was hard fail in that 1st one (as you get more benefit from str as its %based scaling buff). But lets ignore that. (And that 2nd video didnt show build but guessing on numbers it was str/dex hybrid)
Build 1 was
Archer QS3, QS3, QS3, A2? (for crit swift step), SR
And it seemed like running shot did not increased aspd or damage ?
Build 2 was
Archer, Ranger 1, Ranger 2, Ranger 3, A2, SR
If I am correct they rebufed ranger steady aim back to 45% ?
And new limacoln R3 efect is that chain shots to multiple enemies (kinda like ranged swordman splash)?
I know that buff +25% crit rate from A2 is great (but I would want some utility from Scout1) and really hard to pass on it.
To me it seems like build with ranger gives more raw aoe overall as aspd from Retreat Fire, Asault fire seems to be fixed.
