My favorite expansion is Cataclysm. It was the first expansion after I started playing and showed me how much fun new content is.
Wrath of the Lich King was my favorite expansion, and I still enjoy playing that content today!
I started in late Wrath (very late, didn't have a max level toon until Cata). I remember Wrath being fun, but I missed most of it until I went back to play it later. Cata hasn't really stuck with me. But Mists, ah Mists, where I truly raided for the first time, where the stories where (mostly) well told? Mists has to be my favorite expansion.I'm hoping Warlords will be better.
I would absolutely love to win this! I've been collecting WoW paraphernalia for years now! I was legitimately butthurt when I couldn't order this faerie plushie myself as I didn't get the online blizzcon ticket this year!
Burning crusade.
Probably most o pandaria only because its the first expansion I fully experienced raids and all because I just started playing in march. But the best expansion to play through wrath of the lich king. All the zones,dungeons and everything where so much fun!
My Fav was the Burning Crusade. Had fun doing the side factions and reps long after the content had moved on.Meow.
Wrath of the Lich King!
BC was the best by far! Not to mention met my wife in a guild I was in at the time!
Wrath of the Lick King. It was my first full expansion as I started playing at the end of Burning Crusade. It was also my first end-game raid progression.
Torn between TBC & Cataclysm, because I first played WoW during late Vanilla / Early TBC, yet my first serious raiding experiences came later, once I returned during Cata. All those people I've gotten to know have truly been a pleasant surprise!
Wrath of the Lich King, there was when I started to play :)
My favorite expansion was The Burning Crusade, so I cannot wait for Warlords of Draenor to finally be able to see and explore Draenor before it was destroyed.
No doubt: The Burning Crusade. You know, the burning legion, Outland, Kaelthas... so the PvP at level 70. Just wonderful.
MoP b/c of the scenery and mostly because I've been at it from day one until now and going into WoD.It has been the only expansion I've experienced fully and thoroughly.
Cataclysm.
My favorite was my first expansion, The Burning Crusade. It also has my favorite raids. Kara and ZA were both very fun to me. They may have been easy, but they were fun. Plus my favorite Warcraft game was WC 2 and the expansion for it. Those two raids used the lore from that as did the expansion, (for parts of it).
By far burning crusade i think i chose it because it was the first expansion i played and it was awesome to learn the basics way back then.
TBC was probably my favorite, but Warlords is looking really good.
