They made some pretty major design errors by gutting attributes and lamely trying to use perks as a poor-man's substitute for attributable impacts.
They should have let attributes handle what an atributes system does better (interskill effects, strength, jumping, speed, balance, carry weight, etc) and focused on using perks on things a perk system does better (unlocking new skills and abilities (like zoom and slow time for archery)).
Moreover, perk trees that lined up with the major arributes would have made much more sense. Having heavenly bodies named for major human traits like strength, intelligence, willpower, luck, etc.....would have made sense as opposed to having heavenly bodies named for sticking hands in pockets or holding sticks with one or two hands
