Half of MMO-C hates the other half literally all the time.
I only come to this place during speculation seasons and it's always the same thing, fake or not.
WoW expansions get their names months in advance. MoP, WoD, etc. The art and pre-marketing have already been done at this point. You really think with four weeks to reveal, they don't have even a mention of the name anywhere? That's just being obtuse, and doesn't really factor how *Blizzard* develops.
Why would anyone take their info at face value? All of that is literally the easiest fabrication in the book. "Oh it didn't have that info, sorry." They've been wrong even on aspects people claim their leak exists for because of how right they are.
I'm not really understanding your angle. Do you find their leak convincing because it's disappointing? The expac can be disappointing without disappointing leaks just fine. I'm sick and tired of people like therewillbedragons getting attention because people see one "correct" thing and suddenly it becomes the only available talking point.
