I have 24 JP on my level 72 hunter and I honestly don't know how I got them. I thought maybe it was from running randoms like at 80 but I've run a ton of randoms since I got them and haven't received anymore. Where did they come from? This could just be me having an extremely dumb moment but I've had them since level 70 and I don't know where they came from. You don't get them from level 70 heroics as well do you?
