Relax, this is a discussion board, no need to get so bothered by other people's opinions. But what's not an opinion is that Blizz failed their underwater zone, most people disliked it, if you can't handle this fact then I don't know what to tell you.
Can they bring a new underwater zone? Sure. Are they? Probably not, or they're going to invent a way to make that underwater zone not have any swimming and thus no 3D fighting. They'll make it so you can only walk/fight in at the bottom.
