My view… I’ll never understand level-scaling haters (its been a shoulder-shrugger ever since I first saw people posting complaints back in the Morrowind/Oblivian days). Especially when it comes to this genre. I’ve never seen a single convincing argument against it that doesn’t involve “boohoo, I want to go back to early areas and murderize baddies ez” and I don’t expect I ever will. Gear and build your toons even half respectably and this should never be much of a problem anyway. In GD it is all too easy to annihilate opponents that drastically outlevel once you have an inkling of what you’re doing.
Never gunna happen in GD. It’s been in the game from the start (re: literally years now). They won’t rip it out just for you and a few sympathizers. The boat left the dock for that option a very long time ago.
I’d suggest turning to the modders or modding yourself. Maybe in the next GD iteration but somehow I doubt they’ll go for it there either. Best case scenario? Perhaps they’ll make it a toggle but historically Crate is averse to the “toggle-rama” syndrome. Guess it remains to be seen if that mentality holds out in future games.
