What skills should I max for SR3? I know i should max Retreat Shot but i don’t know about other skills.
QS 3 or Ranger variant?
If you are QS3 feel free to put 0 points in limacon.
If you are ranger and just assault fire , retreat shot , concentrate fire and the rest into limacon
just a bunch of text
Im playing an Archer 2 > Ranger 3 > SR 3 build. Thanks guys that was super helpful. 
Limacon 15 is meh as compare to concentrate fire 15 honestly. Since the rotation is better off with concentrate fire 15 for burst then sustain slow shooting limacon
Anyway Limacon is actually for fill in rotation so having it 100% up time will be enough.
For QS since you already have DCG, + divine might it’s near 100% up time there is no reason for you to use C attack limacon might as well drop it for something else lol.

you pretty much have 10 points to do whatever you want to “add into your rotation” instead of picking up limacon (it pointless since 90% of the time you won’t even use it haha… )
QS 3 rotation issue = adding auto attack RS into it. i don’t think you can use AA+ C attack together like concentrate fire
