Bladedancer bug in Shadow clone?

Good night , I have one question with more players using Bladedancer have a problem to uses your skills with needs a shadow clone and your damage dosent appear in mobs because this is my first time playing this class and worried about the class have more issues.

I’m not quite sure what the issue is. Are you using a skill that the Shadows can use? There weren’t any problems that I’m aware of during earlier mp events.
