Ok, well I was bored so I thought maybe I could do Deadmines on heroic up to Rhahk. Well Deadmines doesn't allow. So as sasd as I was I wasn't discouraged! I foud this out. Right Click on your portrait get to dungeon difficulty and highlight Heroic. Run to the portal before you enter click on Heroic. There you go it loads. Nothing is different. Here is a SS. No it is not a on a PS as I am too stupid to get one. If you do it wrong you will just be behind th portal and unale to go further.
