One of the things that just makes me think why as well...I don't see how this even became in ideal. I like that blizzard listens to fans but I feel like this expac has been influenced entirely on people crying for Pandaren over the years on the forums. Pandarens and the Monk class are something people have been crying about forever.
Yes, but it's similar to people wanting guns (boomsticks, if you will) and other technology from not that far after the middle ages in TES. Only a few want it and keep whining about it while the rest of the community tells them to shut the hell up.
About the Pokémon thing. I really think Blizzard are just milking WoW for as long as they can, to finance their new projects or something. I mean look at their "great" Diablo III deal, buy a 12 month long subscription to a dying game and get Diablo for free. Whooptifreakingdoo.
This pet battle thingie just makes the pet collectors cling on a bit longer before they want to abandon their collection and move on in their gaming lives.
It sure as hell was hard for me to give up all my rare mounts which I've farmed such a long time for, but so be it. It was pretty much the only reason why I kept on playing Cataclysm for 1 month or so during patch 4.2.
