[Post Mar 23 update, by the way.]
This was in Arena, my Royal Guard's Taunt was up, and a character attacked someone other than RG.
I was shocked and thinking "Did this really just happen?" when there was a follow up attack against the same character (which confirmed 100%) due to Phasma bonus attacks.
I've used RG every day in Arena and GW and DS missions since the RG changes. I am aware that there are times when the character gets attacked and then the Taunt goes up and that could potentially be confusing to some people, including myself at times.
But I swear that was not the case this time.
Also the character who was attacked was green health, so not triggering the RG Taunt.
I've also seen reports that JC is attacking while Stunned, but haven't seen that myself, yet.

I really wish I had a video of this.
Another possibility would be that someone used an AoE against the (non RG) character, and the follow-up attack (due to Phasma) was as a result of that.
I really don't think this was my imagination. I pay very close attention in Arena for those 3 minutes.
