Blizzard poster Vaneras recently started a poll on the official European World of Warcraft raid and dungeons forum asking players, "What's the most challenging Heroic dungeon in WotLK?"

Oculus is currently in the lead with a whopping 44.91%, followed closely by Ahn'kahet with 16.78% and Halls of Lightning with 16.2%. Azjol-Nerub is the only other dungeon to reach double digits with 10.19%.

The poll goes until Jan. 23 if you'd still like to vote. So which Heroic dungeon do you think is the hardest? Or do you side with many of the O-Boards posters in the thread who said none of them are challenging?
