BC was my favorite :3 Maybe just because it was my first, but I just like the way the gear looks and everything floats!
Burning Crusade would be my favorite expansion, netherwing dragons may be the coolest dragons to date!
Wrath of the Lich King was absolutely my favorite. Ulduar is my favorite raid and ICC is fantastic.
I loved Wrath Of The Lich King cause I loved the Norse Mythology references, the Vikings, Proto-Drakes, and of course the awesome Lich King along with the Frost and Undead Dragons! I also love the lore of the Lich King and how he came to be the Lich King. I like a few of the Cataclysm zones though too, like Mount Hyjal. I love Mount Hyjal!
Cata cuz it was the 1st xpac i played from the beginning to the end
Must've been Wrath of the Lich King, main reason: DK'S!
Wrath of the Lich King was my favorite expansion.
I will honestly say WoTLK. It was an amazing expansion. Some of the most amazing raiding fights. Ulduar is unmatched for a Raid. It also gave me a taste and love for the Death Knight class. Been playing one since 3.2.
Maybe with this I can get a friend to come back to wow!
Wrath of the Lich King!
Cataclysm is mine...having played vanilla it was cool to see the changes it brought to the image of the game and the world of azeroth.
I know it gets a lot of flak, but my favorite was Cataclysm. WoW is very dependent, for me, on who I get to play with, and the group I got to run with during Cata was my personal favorite. I'm hoping to find an equally good group for Warlords, but that's a lot to live up to.
My favorite expansion so far had to be Wrath of the Lich King, but I am really looking forward to the new one.
Wrath of the Lich King and its cinematic intro !
I loved Wotk but i have to admit that i also like the plot in mop :) and the story line and the battle pet.. :P
The Burning Crusade, when heroics felt really rewarding, and the lore felt epic and familiar from wc3(that's why WotLK's 2nd).
My favorite expansion was WoTLK, it was my first full expansion, and when I started raiding.
Mists of Pandaria!Looking forward to Warlords of Draenor!
To be honest vanila was totaly madness :).
I think MoP is my favorite. I love the way the storyline played out over time, chapter by chapter.
