Warning if you do not own the Hellraiser DLC but do own Cenobite
You are unable to use Pinhead in the PTB if you do not own the Hellraiser DLC. Please make sure you have it if you wish to test the changes with the new system using him. You also need to rebuy any characters you may have bought with Iris or Auric Cells in main game, and do not have any of your cosmetics, including Deep Rift cosmetics.
I already made a feedback thread as soon as I saw the change due to the fact that I had to rebuy Michael, a character I main on the live servers, because I do not own the DLC itself. I quickly realized I couldn't even use Pinhead, nor could I use my usual skin of Soma on Trevor. (Soma, notably, has minor bugs relating to his audio and clipping issues, so I was excited to see if they had fixed them.) This is incredibly annoying for anyone who has a lot of characters unlocked via iri shards like myself, who now have to waste a lot of the ones given for free to buy them again.
