I think the rating system likely needs reformed for reasons other than what I show here. Some stuff that @synist3r has covered recently for instance.

But my main reason for putting this together is that people tend to experience frustration with Expectations don't match Reality - and if people are expecting their decks to perform like they did a few months ago... that's just not the current reality we live in.

That's neither good nor bad - it's just different, but people need to understand that difference.
