It looks as though you are playing this role-playing game as you would some sterile, action game. You are chasing achievements instead of playing your character. I am not confident that someone talking about differences between "perfect runs" and "speed runs" is in a position to make claims about "the most fundamental thing there is in an rpg game."
You have a character, an adventurer. His world contains enemies of varying degrees of power. Regardless of scaling, it is to be expected that you will encounter these enemies, and any expectations regarding enemy strength should stop right there. Your problem is that your expectations extend to when and where those superior enemies should appear.
You must have not understood anything from this thread or haven't thought about the thing i'm complaining about at all.
First things first, you can't judge me for a term i used. I assure you it has nothing to do with "powerleveling" practices. They were however the best i found, because in most rpgs i play i start a char to get to know the game a little and then start another one to play normally, find all secrets etc - that's why i called it "perfect" in "...
You new generation rpg players treat rpg games like sterile, actions games, not me! This level scaling trend takes away progression, immersion... everything. How am i supposed to "blend in" with my character when the regular run down bandit has turned to a legendary warrior all of a sudden? How am i supposed to reap the benefits of my adventures if everything scales as i do?
But in the end, you fail to realise the most critical thing of all. Secondary skills are useless. Raising them penalises you more than the benefits you get. That's what i've seen in my 5 characters until now. And that's the main problem of scaling. Don't go making assumptions about "my expectations" or whatever you think i mean, without reading this thoroughly.
Also i'm not even sure that the thing with the regions and certain mobs which are thought were unscalable is a fact. I mean i'm level 15 (with the combat skills character) i finished labyrinthian and ice trolls are relatively easy for him. And that's on master difficulty.
