Yes, you can now only exchange your seats, which you could also do before, but no longer return them. For example, before if you couldn't go to a game you could return them for a credit and use that credit to buy any other seats to almost any other game. Or, like what many people I have spoken to over the years did, use that credit to upgrade your seats for another one of your games.
Now all you can do is exchange ticket for ticket, which I personally dont see any value in. So if I cant make game A I can exchange them for tickets to game B, but I have season tickets so I already have tickets to game B.
