I don't know whether Bioware are aware of this bug, I wasn't until recently. Basically I just started out-of-combat healing while people were attacking me, really really wierd but yeah, I have no idea what's causing it and this was the only warzone where I could do it. It only lasted for the couple of minutes you see there and then afterwards was back to normal. would be great if you could get a fix on this one. Thanks.
