Cata by far my Fav! But I am learning to really love Pandaria.
Right now, my favorite expansion is Warlords of Draenor, on the 6.0.3. pre-expansion patch.I say this cause, since I started playing on 4.3 Cata, I only see the game going better and better, never declining.So, for me, the best state of the game so far is the most recent one.
Definitely The Burning Crusade. Oldschool LFG at the dungeon portal beats all! Also the content was way more interesting, hopefully Warlords will meet my expectations.
I liked BC for Illidan Stormrage being my all time favorite from the lore perspective, but MoP would be my favorite expansion by far since I absolutely adore monk healing. Well, that and they included red pandas for females as a nice surprise when I made my first.
I enjoyed Wrath of the Lich King. The story was so deep and absolutely gripping. Not that any other story from Warcraft isn't, except maybe cataclysm, but Arthas' story line was one of the most gruesome and heartbreaking story that I've read about so far. Thanks for the contest! :)
Been playing since Vanilla and I gotta say my favorite expansion was Wrath of the Lich King.
Cataclysm, always loved dragons and the Aspects and even tho it was long i loved it.
My favourite expansion so far is Cataclysm since I started playing just before it's pre-patch. I witnessed how the world changed, and I was amazed^^ I've been playing a mage and the class was more stable back then too (although I have to admit the playstyle has been getting better since MoP release). Additionally, the content was not too intense compared to MoP so to say, so I had a lot of freetime to go explore the old content too.
I loved TBC best exp ever
I'm gonna have to go with Wrath of the Lich King as well for my favourite expansion. It introduced so many of the features that we grew to love. Right from the release of that haunting cinematic, it was phenomenal.
Cataclysm because of Kalecgos <3
For me it's TBC. Good villains, raids weren't all about skill but also a lot about gear. First arenas were also amazing, i was shaking all the time :D
Cataclysm, if only because that's where I started. It may not have been the 'greatest', but it's got some awesome memories for me.
Favourite Expac: TBC 1/2 and MoP 1/2. Having played them all, TBC had the ability to build a reputation on the server for good players or prominent personalities. MoP I have enjoyed for the developments it brought to the game, but it is far more casual now. It requires less dedication to acquire "serious" loot in the game, rather than heroic instance blue's (which in TBC were no mean feat either!).
Burning Crusade was my favorite expansion. Great raids and progression along with leveling zones competing for territory.
Wrath of the Lich King :)
my personal favorite expansion was wrath of the lich king,WotLK was my fav expansion because of its unique story line and the fact that most of the gear was blue which makes for some cool xmogs
My favorite expansion was TBC. I started playing WoW then. We were a large group of friends playing together and I had some of my most memorable experiences in WoW when I played TBC.
My favourite expansion was probably MoP because even though I loved the previous expansions, especially BC, I didn't feel like I was a part of the storyline and end-game content until Mists. Maybe because I was stuck in my noob phase for actual years ._.also pandas are awesome so yeah
Probably The Burning Crusade. Tons of new lore was probably the best part of it.
