I don't follow your logic, the badits scale so you are challenged, so you are continueing to improve your combat skills, so that you can increase to the point where you can fight enemies that begin at higher levels and will not scale until you reach their level, and repeat to continue to advance whihlst being challenged. And many do find skyrim enjoyable because of this.
Frostgiant i'll say it again: 21 level with perfect gear was a lot harder than 5 level with starting gear.
Meaning that i raised secondary skills in order to get benefits (gear etc) - which should be "secondary non-combat skills" point. But the levels i got with these secondary skills gave me a penalty instead of a benefit.
Examples:
Crafted potions with alchemy - harder enemies while having these potions, easier if i didn't craft them at all.
Raised picklock/pickpocket to steal a powerful sword? The levels i got from this made the iron sword i had at the start look more powerful than that sword i stole.
Forged powerful armor? The starting armor seemed to absorb more damage after getting some levels from smithing in order to get that armor.
I would not mind if they scaled just on combat skills. I could live with it. But the benefits non-combat skills give you are none in practice. Only decorative. You are better off not raising any combat skill if you want to get progressively stronger as in any rpg instead of getting progressively weaker.
