I will forever be in love with the Original Deadmines. There was nothing like Mr. Smite and I use the trinket all the time.
My favourite instance by far is molten core.
Halls of Oringination :} I just love the feel of the place.
My favorite instance would be ICC. Arthas is my favorite lore character, boss fight, and has the coolest looking raid in the whole game!
BRD, the first instance i ever visited ... and it took several hours :/
My favorite instance was the Temple of Ahn'Qiraj. It was expansive and there was such a lead up in events for it.
I like Ragefire Chasm the best. Simple, easy. I hate all these new instances which are more about fun annoying micromanaging in combat rather than actually killing things.
I'd say Stratholme just because of the massive amount of time spent trying to get the mount there. And this was back when you could reset it not just once a day
old scarlet monastery!
My favorite instance is the one where everyone does their job correctly, no one whines and fusses, and we don't take an inordinate amount of time to complete it.
All-time favorite instance is Karazhan.Weren't there whispers pre-WoD of a revamped Kara?Maybe we will be treated to a Timewalking version?
Well for dungeon wise I'd have to say The Violet Hold but for raid wise I'd say Siege of Orgrimmar. The Violet Hold was always a simple dungeon that people often got bored of. I loved it for power leveling and other things. Siege of Orgrimmar was my favorite for when you had to pug someone in. Everyone had that one group that you swear the people must of had something wrong in the head dying to something that was super easy to avoid. Watching someone die because they stood in a pool on Immerseus or the adds before Sha of Pride murdering peoples faces from the tank gathering them all out and them being aoed to quickly! Was always a fun time watching it happen.
My favorite instance is the Well of Eternity. Completely unique visuals.
Karazan was the best such a story such an environment
Black Temple - TBC is where i really started and to this day i can quote Illidan and Akama's dialog.
The Forge of Souls! I love that instance, the music and the chill ambient there is :D Also the big razor blades on the bottom is pretty cool! :3
I love Black temple cause every time he says You are not prepared i laugh and say I think iam now :P
I would have to say my favorites were Ulduar and Icecrown Citadel.
Ulduar. Great music, awesome environments, memorable encounters..... Literally the perfect raid.
