I feel like this is really skewed. To say something about the top tier of players is fine. Which is what this is talking about. The “best” players in a certain field. I’m a 2300 player and a heroic raider. Which means I’m not included in that list of people. If I’m not included, many other people aren’t included either.
That said, we know from other websites the player base is much closer to being 50-50 based on numbers. So, this seems more doom-and-gloom than anything else.
