It can work, you’ll have to skill reset most likely though. Take Full Draw and Oblique shot, at least level 1. Full draw for the semi-stun, knockback and def debuff. Oblique shot for the slow.
We took the same class path, and I pretty much quit when I saw my backstab damage(I started working on my swordsman). However, after re-assessing my build I was able to create one that had significant damage output and pvp feasibility but had to either take cannoner or musketeer at r7. (You also drop backstab altogether)
Here’s where things get a little iffy, this build allows you to go plate armor as you will be taking the evasion skill. The skill adds a flat amount of evasion % which you can utilize with a tankier plate build. (Evasion level 5 gives you a flat 50% evasion chance, meaning enemies will miss 50% of the time even without any dex.)
You’ll essentially be using Rifle + Bow or Rifle + xbow and shield.
