New Mighty Swing skill doesn't show animation properly

Roxxannae - Sanctuary

I was duelling a Barb friend with the new Mighty Swing skill or whatever it is called and was admiring that it paralyses me or "knocks me over". He went to test on another person and I noticed that they just stood there and didn't fall over. Upon asking it turns out nobody could see me falling over at all so they had no clue what I was talking about b:laugh

Basically from what I can see, only the person doing the skill and the person getting hit can see the "falling over" animation from the paralysis.

How to reproduce: Witness a Barb use the skill on someone else.
