Chased by the tanking training dummy

So here's a weird glitch for you: today I was practicing the balance druid rotation with the legionfall buff on me when the tornado from the buff came up and knocked back the tanking training dummy. Apparently that caused it to lose it's usual inability to move and I proceeded to be chased down and murdered by the training dummy.

I feel like Blizzard are trying to tell me that I suck so much at balance druid that a training dummy could kill me lol
