Here’s what I suspect happens:
• Illfonic releases a DLC which has very, very good stats (a subtle ‘pay-to-win’ setup). People buy it because they want the most powerful character (despite it not really being a Pred, more of a space Viking).
• Knowing that this character is OP, they shadow nerf it in subsequent updates. Because they don’t release detailed info on the attributes of each class or DLC, they can get away with this.
• Repeat for next DLC character and count $
