My favorite part would definitely have to be the farming portion of the new continent. I find the farm lands to be a rather interesting new aspect of the game. The entire Valley of the Four Winds is a very fun and entertaining zone. So to re-iterate; the new Cooking and Farming aspect of the game!
following the quest lines
Favorite part? Hrrmmm tough one I really like the Elder Coins, another chance for epics is very nice!
Farming! I love my farm in Halfhill and I wish we could expand it to trees, bushes, flowers... it so relaxing.
I especially love the new Rare-Spawn items and weapons scattered throughout Pandaria! Very fun to go searching for them =)
Brawlers Arena for sure.
AoE looting and Item upgrades are two incredible additions to this xpac. Loving this expansion so far!
My favorite part of MoP is all the new mounts, and Pet battles...I also love the AoE looting...makes farming dungeons so much faster :)
My favorite part of Mists of Pandaria are definitely the raids. The difficulty in the current raids is challenging in a good way - they actually make you work to get a boss kill! I also love the idea of a farm and the return of world bosses.
I really like the idea that the Pandarans have no idea how the thoughts of the foreigners will affect their part of the world...it leaves this massive cliffhanger of expectation!
The best part of MoP for me would have to be, World PvP. I thoroughly enjoy what they've down with it compared to the last two expansions. Brings me back to my days at the Halaa. Now if they could just make a 40v40 Arena/Raid :)
Believe it or not but the DAILIES!
My favorite part about MoP is the fact that it's something new. No, I don't mean a new expansion. No, I don't just mean new content. I mean new. New lore. New raids. New factions. New continent. Everything has been created for the sole purpose of this expansion and Blizzard knows that if what they are doing here is going to be successful, than they have to do it well. And they did. Maybe there are too many dailies. Maybe there is just a little bit TOO much to do, but people fail to realize they have an entire expansion to do it. I love the simple fact that it's a breath of new life into WoW.
How balanced arena is.....
My favorite part of MoP is the Pet Battle System. It brings back memories of Pokemon. Gotta catch them all! It is such nostalgia to have something in the best MMORPG game ever made. Blizzard is INCREDIBLE! Kepp up all the incredible work with all the games that you make!
My favorite part so far is probably the tigers. They're just so damned awesome looking. If I have to giver a broader scope sort of thing, I'm torn between Kun Lai and the Wilds. I like how in Kun Lai you seem to actually make a difference; I like jungles, thus the wilds. In both, I'm fond of how there's just random quests you can find on the way to the assigned quest destination. It makes it seem like you're discovering something rather than just traveling to point B, killing &*!@, and then returning to point A.
AE Looting is the best!
My favorite part of MoP are the addition of many Rare Elites throughout Pandaria
I really appreciate Blizzard's efforts at improving things for convenience and whatnot.
