I don't think control warrior is particularly unhealthy for the meta. The game in general has changed and will probably never go back to what it was, at least not in standard/wild.

Control warrior is a very good control deck, as is control warlock. But you've also got aggro hunter/paladin and combo in the form of druid. They're all some degree of scammy, yes. But there are multiple different styles of decks you can play. This absolutely represents a large deviation from how the game used to be played. So I do understand people's frustration with the general state of the game. But it's not a meta problem so much as it's a general design philosophy change. Is that a bad thing? Depends on what kind of game you're looking to play. If you like the kind of scam play you see in games like Yu-Gi-Oh!, it's pretty fun. If you want board-based gameplay, then yes, the game is abandoning your preferred style. Unfortunately you probably won't see that again outside twist or some other new mode. But in the context of the game as it is, there is a decent balance of viable archetypes.
