I was getting frustrated with the blade dancer special, too. BUT, I'm getting familiar with the sound it makes when someone activates it, and of course the animation, so I run away until it ends. Got chased while on first light, trying to take a zone. Saw dude activate it when looking thru the window, so I ran around the building until his arc blade expired. By that time, a teammate showed up and killed him instead. One of many Benny Hill moments I have in crucible.
