Daggers Drawn attacks can miss.

I was also thinking that the skill is worthless, but it benefit from your dext, and deal WAY better damages than 4 normal attack when your dexterity hit 12+.

When you miss a hit, your target will turn to face you ONLY the FIRST time.
I didn't find that to be an issue when:
-your hit chance are really high if you have the corresponding trait (+20% hit chance on backstab)
-you can't miss on stunned/tripped enemies
