Let's look at it this way:
Where is the challenge if only the Player gets stronger?
If you're talking scaling, the challenge would be set level ranges for certain areas. Higher level stuff would exist in remote caves. Low level stuff near roads etc..
The problem is there is no challenge currently. You can mow through everything easily at level, except when you randomly get 1 hit killed by a spawned 2 handed weapon user. Or if the camera goes wonky and you can spammed by Ice Spikes from a caster.
Combat feels almost identical at level 50 as it did at level 1. Block spells/heavy attacks. Swing for the fences. Cast spells if you feel like it. Chug potions when in trouble. I guess there are some high level perks for weapon skills, but do you even notice?
The only one I consistently remember is sneak/stealth 6xdmg kill. But at level 1 I didn't need 6x dmg so the gameplay was almost identical.
I guess I'm more akin to as my character levels up, I would get more complex abilities or advanced spells etc... I've been conjuring a flame antioch since level 5 and self healing. I guess I have more shouts to use now, but most fights are over after 1 shout and still waiting on refresh.
Maybe I picked the wrong perks? I have a bunch in 1 handed and shield. Shield blocks magic now, that's nice. But NPC magic is so overpowered that it was a must have.
