The next World of Warcraft expansion, Mists of Pandaria, and many of its new features were announced this weekend. I sat in on some of the BlizzCon panels, where many of these additions were explained in detail. These include the new (neutral) Pandaren race, the Monk class, a level cap of 90, a complete redesign of the talent trees, a PvE scenario system, dungeon challenges and leader boards, and many new zones, battlegrounds, dungeons, and raids.
But in my opinion, the best feature that is going to be added to World of Warcraft is the new pet battling system.
This is basically the game I've been wanting since I was in the second grade.
Let's break it down.
At one point in my World of Warcraft pet collecting career, I had over 150 pets, putting me in the top five in the world for number of pets owned at the time. Since I stopped playing World of Warcraft, dozens more pets have been added, and the top collector has almost 200 pets. I never really cared about raiding or gear, all I cared about was getting the newest, coolest pet (and mount), and having everyone ask me where I got it, how long it took me to get, or how much gold I had to throw down for it.
That was when they were called "non-combat pets", and they did absolutely nothing other than follow you around. I don't think it will be the Pandaren race, Monk class, or the nine new dungeons and raids that will pull me back into WoW. I think it will be the release of what will essentially be a Pokémon MMO.
While complete details weren't available, we learned quite a bit about this new system from a BlizzCon panel.

The almost 200 pets that are already in the game will be able to battle right from the start. All the pets you have are combat ready, and if you've been hoarding pets, your hoarding disorder is about to pay off.
If you don't have a huge stockpile of pets, there will be new wild pets that you can catch and train. To keep track of all of this, you'll receive a "Pet Journal" (read: Pokédex) that tells you about all the pets, where to catch them, and what you need to do to get them to join you.
If you're too lazy to actually go out and catch the pets yourself, many of them can be traded with other players. Your pets well be stored on an account-level, and will no longer bound to a single character. meaning you won't have to spend another 20,000 gold to buy a second Hyacinth Macaw for an alt.
Battling with your pets is similar to Pokémon as well. You can go into PvE or PvP turn-based battles with a team of three pets. If you win, you'll gain experience to level up your pets. As your team gets stronger, you can take on the "Pet Masters" (read: gym leaders) scattered around the world. Beating them gives you a master ability (read: Hidden Machine) to teach your pet.
While the system is planned to be large, don't expect to level up to 90 by just battling pets. Blizzard has said that the pet battle system won't be providing any rewards that will affect your general PvE or PvP progression. It's something to pass the time, not a replacement for questing or battlegrounds.

That's most of the information that's been released so far. As the unknown release date for Mists of Pandaria approaches, we'll likely see more specific information, screenshots, and more details on the actual pets themselves.
Rest assured, though, I can already tell you that my Kirin Tor Familiar is in the top percentage of Kirin Tor Familiars.
I will crush all comers.
Congrats WoW, you've broken social physics. I understand how to have zero respect for you and your players; but now I've got to figure out how to deal with this negative amount of respect.
Of course ever since the first expansion the game has pretty much been about only making any animosity cross-faction exist only in the sense of regulated, scheduled PvP in designated areas and otherwise just completely blurring out what was the original point of the entire fucking game: ORCS VERSUS HUMANS.
Not "humans and orcs team up to battle larger threats to the world". Why even have god-damn factions at that point, except to artificially segregate your playerbase? There's pretty much zero story left at this point that would have the factions exist at all. And a neutral race pretty much just puts the last nail in that coffin.
@jjcobra - I like WoW, I like Pokemans, I like WoW Pokemans. Come at me, bro!
Smells like desperation. ><
The general mechanics of the game is over 6 years old now. Every expansion is more of the same.
People are getting bored. Icing like this pet battling mini-game I doubt is going to cut it.
From what Chris Metzen said at the opening ceremony, Blizzard is changing all of that in MoP.
There isn't going to be one big boss that the whole expansion is leading up to. The story will revolve around the horde and the alliance bringing their war with each other to Pandaria and getting the Pandaren involved in the conflict.
But i don't care, i'm all hyped for guild wars 2.
Don't worry, we don't respect you either. =)
Looking forward to reactivating my subscription when this expansion comes out. The "PokeWoW" really did it for me.
It'll be interesting to see how well they can steal the Pokemon MMO idea that everyone thought should be made.
I haven't played in over a year because I've been too into fighting games but this definitely peaks my interest and I'll be coming back..
Hmmm... ;-p
Way to miss the point.
Mabans and DasPooch missed the point that their stupid
Oh, and it's amazing how many things they have ripped of of Guild Wars 2. Yes, even the Pokemon. It's all there, already in GW1.
WoW is F2P. F2P until you're lv 20.
You don't have to publicly try to convince yourself to not come back by hating on it.
As far as WoW dying, even if it lost 80% (which is a huge amount), they would still have a couple million. 2 million is plenty for an MMO to survive and grow. Look at Everquest and Ultima Online: those games are still alive today, and they are ancient!
