A bug I've been seeing continuously is being stunned out of hunker down. I've had it happen to me about 3-4 times yesterday. Whether it's latency related or what I don't know but I'd use hunker down, the bumpers would come down, and a sorc or something will 4 second stun me through it. My hunker down then proceeds to go on cooldown after I get stunned through it. Really frustrating.
