So basically what you're saying is that you'll gripe and moan about anything Blizzard says, even if they are telling you that they're going to fully support the game and provide regular content updates, and already showed as much before the expansion is even released.
I'm not saying I know one way or another, but jesus christ dude, stop talking about Blizzard like it's your ex. It's a game company. Anyone with common sense would know that Blizzard is very likely not lying about any of this because they are desperate to reinvigorate the game and earn trust back after WoD. At the very least, wait until there's actually signs of something questionable before you start complaining.
