Difficulty scaling makes character progression completely pointless.
Why would it make it pointless? If a PC is overpowered due to his/her build and the difficulty scaling ai decided to increase the power of the monsters spawned (in some or all areas), wouldn't that be a service to the PC's progression?
Scaling goes either way up or down in difficulty.
p.s. Anyway, I can already foresee many disagreeing with what I posted cause these are features that the player shouldn't know while playing the game. I'll just leave it at that anyway.
Further Edit: what I meant originally for difficulty scaling was a consistent challenge rating scale. My bad.
When I talked about level scale, or difficulty scaling a.i. that was when I was referring to the environment being changed for the player.
