1) It doesn’t matter whether it affects other Diamonds or not. That’s irrelevant. It turns something ostensibly intended to be special into something trivial.

2) Why NOT have another tier? Once upon a time they stopped at Platinum. Who’s complaining now that there’s a new tier above Platinum?

3) Who does it hurt to have another published tier that can’t be diluted by credit card shenanigans?

4) The more tiers, the merrier. Have 200K/$24K, 325K/$39K and 525K/$63K tiers while keeping the D360 Pegasus. That’ll effectively end MQM rollover, so be it. I may not make the top tier, but I’d happily live with that.
