You may be aware that a blue drake mount now drops in HC Occulus but only if it is picked as the random HC dungeon, you can fix the random dungeon finder to get the dungeon you want, in this case HC Occ, but you can also do this to do your Emblems of frost in a ICC 5 man to try for battered hilt.
When you have entered a random HC, if you watch the loading screen you can tell which dungeon is coming up, if you don't like it: hold alt and F4, you will be saved to that dungeon and 15 mins later you can enter another without clearing any bosses.
The beauty of this is that the random HC finder has less chance of giving you an HC your saved to, so you can fix which instance it will random by deserting other players then trying again. If your a tank or a healer and you get instant queues, consider doing this if you no longer need triumph![]()
