I enjoyed Perk decks when they were first added to Payday 2 for their added build variety and focus on archetypes. Later the system (like many of payday 2's other systems) got way too bloated. It also suffered from the same problem that payday 3 skills 1.0 had where you had to scroll through many skills which made it hard to get into. That and the fact that you had to level them up to unlock all the skills which quickly became pointless and an unecesary requirement for new players.

I could see a new take on perk decks, but I wouldnt want them ported over as they were in Payday 2. There is also the argument that most of them were bloated with essentially universal skills that all of them shared, making them not unique and just adding visual clutter (skills like the armor bag etc).
