Tbh, why should we believe you Op?
If you at least provided a screenie with the chat with censored name or something... I mean first it's just random writing, and even if there was a conversation we only get your interpretation of it. You must understand why people don't really buy your post as something true?
I think a lot of people want to work at Blizzard because they love world of warcraft, and I think that with the lore and the world there are enough ideas and excitement to keep good enough people caring for the game. However, working at customer support with little to no abilities to affect the game, just listen to customer whining all day... makes people a little tired, no matter what kind of customer support business it is.
And can we blame them for wanting to play the new games, and want to develop them to work well? The new games are the future games, they can only grow in popularity while with wow it's just about maintaining... and grass might look greener on other side for some people. And sure, wow might not get same attention as it did in the past, but it's probably getting attention enough, even though it might not feel like it in game atm and in upcoming patch... we don't know what future holds for wow, and neither did your friend it seems... since it was just about upcoming patch which there is a lot of dissatisfaction for on this forum, and also adds another probability that you are posting a somewhat not thrustworthy post, because you aren't really happy with the game atm.
