Hi, sorry for lack of clarity. I am a brute and before patch the mobs hugged me tightly and after the patch a few of them just suddenly run away, perform a few ranged attacks and then come back next to me. I am a Rad/Fire brute - I can't say for certain which power is causing it, I can test further. What I do know is that I seemingly don't have as much agro as I used to. Hope that helps.
