MoP because it was my first time raiding and raiding is fun as hell
I only played Lich King and Pandaria, so... I think it's Lich King. More motivating and mysterious. But Warlords of Draenor seems to be epic!
The Burning Crusade has to be my favorite since it introduced the least changes to classic WoW. Also, a "new" world & expansion was something novel and we did not know what to expect. :)
My favorite expansion so far is BC
Burning Crusade was pretty good imo, lots of fun content to go through, even today.
burning crusades for me
My favorite expansion was the Burning Crusade. Yay flying mounts!
Wrath of the Lichking for sure! Ulduar and ICC are still my favorite raids.
Wrath of the Lich King, Frozen Throne was my first blizz game and it was awesome to see Arthas throughout all of that xpac.
Definitely WoTLK simply because of DK's and I really loved the mounts, dungeons, and raids.
For me, it was The Burning Crusade. It was the first expansion where I had the opportunity to raid the endgame content that World of Warcraft had to offer.
Burning Crusade would have to be mine. It's the first Expansion I had the chance to play from the start to the end while it was current. Good friends were made and good times were had. Was also an expansions of a lot of first for me in terms of raiding and season 1 arena.
My favorite expansion is Warlords of Draenor. I am really excited for the garrisons!
My favorite expansion was probably Cataclysm. I really enjoyed being "back" in Azeroth, instead of spending all my time on other continents/worlds. The visual updates and the refactored leveling experience really helped give WoW a much needed update; even though I still personally miss the old Barrens... lots of great leveling memories in that zone.
Wrath of the Lich King was my favorite expansion. I loved the lore, zones, raids, dungeons, everything! I started playing in Burning Crusade but Wrath is what really got me into the game.
It's hard to say what my favorite expansion is, really. Wrath of the Lich King and Mists of Pandaria both had many things right. Wrath though still had a lot of stuff wrong, and Pandaria didn't go far enough in some newer things. Too bad WoD is a complete reversal back to its old, antiquated basics.
TBC no question.
Wrath was my favorite, not sure why but it might be because it was when I first started playing, so it has alot of memories attached. On another note, I really want that plushie!
I started a bit before it came out, but Wrath of the Lich King is the first time I got to all the epic content.
I think my favorite would be WOTLK. Loved progression raiding during that time. Who knows Warlords could be my new favorite!
