As far as I can see is temporary but who really knows.
Current system is no fun in log run even if working and predictable.
Preferred much more randomness of old backgrounds and stat growth. It was more enjoyable and allow some unexpected guys grow strong. Now its only few vial able backgrounds for End Game Dream Team.
Devs promise to rework whole stat and perk system and seeing how they mean business I hope they will do it and do it well. But we will see.
