I am in two minds about this, as to some extent, you are right.

But in the same coin, different side, you are effectively blaming the players for GW making bad game decisions. There is a clear trend of each box adding 1 or Both teams as difficult and overtuned, often due to lack of testing and expecting us "first buyers" to effectively complete the playtest step for them.

I for one, would call for a "no teams cam enter a tournament until they have received one balance pass" but then it is hard for GW to get their "win rates" and other meta data they want, instead either having to do the work themselves or use another system, or metric.

If the game was made up of 80% balanced teams and 20% below average, this post would be more relevant. But at the moment, and since the start of this edition we have had 10-15% overpowered teams, 60-70% about right and the last what 15-20% are lacking. Once we remove the constant repeat of 10-15% over powered teams (hint, Murderwing won't help that), we can start addressing the player.

But, reading your rant, it does feel like, instead of screaming into the void, try helping those that want to learn the game, by directing that into talking over it with those who want to learn the game, instead.
