Not done it on either, had a peak at the entrance when low level but not been in a rush to do it. I guess with the dlc a week away I had better get my arse in gear so if anyone would like to join me on normal mode at some time this weekend you can add me if you like. I am on ps4 gt: RegnakUK, am on uk time and will be on about 7 or 8 pm if the missus goes to bed early
