Well they are giving in to the kind of player that dont really want to play a MMORPG. wow is slowly but steady being turned into a singel player game where you collect various stuff.
I have never understood why people decide to play a game in a genre they dont like alot, then demand it to change in so many ways that its getting hard to put it into the category it first belong to. In WOWs case its MMORPG.
People also like to say "oh well but they have it in this MMO, so it should in wow to". Well newsflash, most MMORPGs out there are shite in success compared to wow. Features in other games that arent in wow shouldnt automatically come into the game. Many of those MMORPGs are bad for a reason.
The formula Blizzard has used and are for some weird reason steering away from now, did work. Slowly but steadily the people crying for singel player features put into wow, with Blizzards aid, are putting the light out of a great genre in the gaming universe.
Alot of popular games are "lul log on, lul kill/loot stuff for 1 hour, GG gone lul". wow dont have to be that. The MMORPG genre is one of those genres where if you put into effort and actually dwelve into it, you get SO much in return. Unlike most game genres out there.
