IF you have ever been to DT they use the new skills. there...
When your screen flashes while for a few second a ARche rjust hit you with blind shot..
Those yellow slow arrows that be on the ground... Those are Slow shot.
Those flame shella thing that do uber Damage... They use Flame walker....
Rangers get hide,entanges,boobytrap,utmost shot
SS get blind,slow,distant,disarm,detect,utmost shot
+ the extra power/aims
they both get Utmost as you can see above and the aoe bleed also the dipper/release.
Maybe there is more skill that will be released butfor now if this is the final output i will be going sharp shooter.... but if there is some magical dex buff for Ranger i will go ranger
Also although SS get the power hting skill the Ending xbow had double the power of the Bow.
