Azjol-Nerub, I guess. So pretty!
Ulduar
It's sad to see Timewalking as just another concept watewred down by WoD, and having any hint of originality removed.I used to love Shadow-Labyrinth "TIME FOR FUN!" but the Timewalker dungeons are but a withered shadow of a former greatness.
I'd have to say gnomeregan for being my favourite instance.
My favorite instance has to be Grimrail depot, I really like how you can see the world moving around you in that one.
I love the Iron Docks,Why ? Because all fights are on open area and air ,it makes atmoshphere more lively.
Grimrail Depot, for me.
Ulduar = best raid!
Violet Hold
Karazhan by far, the music, the scenery and the atmosphere are amazing!
My favorite would have to be...........Magisters' Terrace.
Favourite instance - Karazhan
Probably still would consider Icecrown Citadel my favorite instance. Mostly due to the attachment to the lore associated with the Lich King. Enjoyed the textures and design of the lower section of Siege of Orgrimmar as well.
stonecore
Karazhan I always did love the many level & layout of this instance. Is it true there be a revamp Karazhan for WoD?
My favorite instance in terms of raiding would be Blackrock Foundry because the graphics are amazing and the bosses are so much fun. Really cool to work with others for one goal
My cat destroyed my turtle beaches headset, made my dirty shirt pile a toilet and ate my other reptilian pet. I hope Wowhead can help rebuild me lol.
I have fond memories of Throne of Tides and Grim Batol :)
Throne of Thunder ftw.
The Forge of SoulsForge of Souls with the other instances, and the entire Icecrown Citadel raid is my favorite.
