Sorry, I’m not buying this reasoning. Scaling exists because D3P wants to spend as little effort as possible on mission design. They hope that it will somehow balance out to give every player a reasonably challenging, maybe even enjoyable game experience. They are either blissfully unaware that they have failed in every regard possible or they simply don’t care as long as the money keeps coming. Possibly both.
If you really believe scaling is fine and working as intended, please explain why we haven’t reached any major progression reward for ages now. Do you want to imply those are just around to goad us along, never meant to be collected?
