On 11/25/08, I did Oculus for the first time. I did it on my hunter.
Since then, I have done Heroic Oculus precisely once, on my paladin, for my Champion of the Frozen Wastes title.
Random heroic for my hunter today? Oculus. On the bright side, I got the achievement for the heroic version of the dungeon (over a year, a YEAR after I got the regular one) and Ruby Void and Emerald Void.
But ugggggggggggggggh. I hate that place.
