This is where I stopped reading this ;-)
The fact is it is broken and only to what degree is debatable.
“Broken” is a sensationalist descriptor in this case. The DR/SR system clearly works as intended. Just because collective minds can come up with improvements to it, doesn’t mean it’s broken. To be broken would suggest it doesn’t do what it’s supposed to do. To be clear, being able to game a system isn’t a requisite of being broken - just in need of improvements.
The only thing I’ll agree that’s broken is the Penalty System. Specifically, the judgement algorithm. I believe you & others are conflating the penalty system and the SR system, which I could understand because they work hand in hand.
