Today's patch notes mentioned that Sealed events will now try pairing people of similar (presumably Limited) ranks, something which doesn't occur in Traditional Draft events, but does to some unknown extent in Ranked Draft.

This is nonsense in both cases, but particularly with Sealed which doesn't even have a ranked component. As has been pointed out by many others, yet bears repeating, players should not be punished for good performances when their resources are at stake.

If MTGA devs want a limited mode where rank or MMR matters in the matchmaking, they should create a F2P mode where the only thing at stake is your rank and not your money (hint: make Ranked Draft a phantom one).
