Forge of Souls has to be my favorite, it had the whole James Brown thing going for it. It was cool running such a gothic horror instance with funky soul music playing instead of the standard creepy music.
Blackrock Depths...no other 5 man has this many bosses
Ulduar favorite forever
my favorite instance is tie between Ulduar and Vortex Pinnacle
My favorite instance in World of Warcraft is: Pit of Saron
My fav is The Deadmines
Dragon Soul ofc, there are none like that one :)
Black Temple.
Ulduar. Deadmines when it was released.
My favorite instance is Dragon Soul.
Pit of Saron is the one I spent most of my time in WoW - those items farm pre ICC... FMLAs beauty and atmosphere it is definetely Ulduar with large margin before BT and Firelands.
Zul'Farrak. I've always enjoyed that one.
The Deadmines were my first and favorite. You don't forget your first!
Out of all the instances i've been in, I would definitely have to say that Firelands is my favorite! The whole zone is just so creative and beautiful!
My favourite is slavepens.
Favorite 5 man is Maraudon or Shadowfang Keep. Favorite raid is tied between Zul'Aman and Karazhan. The design on those dungeons continue to blow me away.
My fav one is serpentshrine cavern. love the entrance
My favorite instance is Ulduar! The first time I saw it I was absolutely blown away.
I have to say, Ulduar is a must. It's a long one, but once it is done, it's rewarding :)
Big fan of wrath and the sheer epic quality of ICC. Ulduar is excellent as well but I gotta put ICC first
