"The shot deals normal damage if it hits"
I'd love a normal damage armour sunder if it means they don't turn and hit me for over 2000 damage immediately after they run a short distance away from my melee attacks. Seems to do 750-900 mostly (on threatening), but also often hits me for around 2000 so that's possibly a crit. Given the full draw charged shot hits for about 350, I think someone either missed a decimal point or as Chi suggests above, the skill damages are swapped from what they should be.
True, once you get used to triggering/spotting the run-away animation you can limit how often this happens. However, the damage is so far above everything else and is 100% triggered by a common enemy if you engage them in melee without outright killing them. As such, I can only see it as bugged or improperly balanced in my opinion.
