BURNING CRUSADE ALL THE WAY
I think that i like MoP, since i justo played one month of TBC, and came back to pandaland.
I got a conflict because i love almost all expansions! Perhaps my favorite was TBC due to its challenging Raids, but the Wrath of the Lich King was also amazing for me regarding the mere fact of fighting the same Arthas you drove into greatness in Warcraft III, but all the game improvements included in MoP and the very pandaren starting area are also amongst my favorite things.... so.... I'd say that i just love World of Warcraft... (Not cata xD)
Wrath of the Lich King was my favorite. I started playing in the middle of Burning Crusade so I was at level cap when Lich came out. It was all very exciting.
my favorite was The Burning Crusade, cause Draenei were presented there and the changes it bringed to the game. )
I think that burning crusade has to be my favorite. I ton of my friends were finally getting max level toons and we were able to start raiding and getting into the actual meat of the game. We would spend entire weekends camped at someone's house with six or seven computers all in the same room. It was a regular occurance for a while.
Great Job Blizzard
I liked the Lich King expansion the best
I started wow back in BC ,but man, i gotta say,after Wrath of the Lich King came out, I was playing WoW non stop.The Death Knight is my favorite class since then so basically Wrath of the Lich King is my favorite expansion of them all.
Burning Crusade was my favorite due to all the Legion influence and sci-fi aspects to it. Warlords could overtake it though depending how it develops.
I'm new player, only expansion I know is MoP so I can say that this is my favourite.
My favorite was The Burning Crusade!
My favorite expansion pack was Wrath Of The Lich King. Oh man do I miss hunters having mana and the eyes of the beast spell. Haha, Good times!
I loved MoP! Why? Because pandas, thats why! :3
Cataclysm for sure! I just love the elemental and the Tol'vir storyline and quests! Cata was an expansion with a great content, like really cool pets and mounts, whitout mentioning the amazing raids and dungeons!
CATACLYSM
I've been playing for Wow since Vanilla, and I'd say for storyline, that Wraith of the Lich King was my favorite, but that for visuals Blizzard did an awesome job with Mists of Pandaria, and we finally got Pandas!
TBC, simply because of the nostalgia I have for it - it was when I started playing.
The Burning Crusade.One word: Karazhan. :P
Wrath of the Lich King was my favorite expansion. Mostly because of Ulduar, which is my favorite raid instance, actually no other raid or dungeon comes close to Ulduar's greatness (maybe Karazhan!).
