Still, I've been thinking about how the Skyrim experience can be improved even further... and it hit me. A change in the traditional system that is bound to displease some people, abolish levels altogether. Bear with me.
The only point of it is to add 10 points to Mana, Health or Stamina and unlock a Perk... and create a basis for level scaling.
Instead get rid of levels. When you first create a character you have a certain amount of points (let's just say 300) you can add to either Health or Mana, depending on what you want to play. Stamina becomes a trainable skill (while arcane talents (Mana) physical robustness (Health) are genetic and can't be enhanced without magic, I think it makes sense from a realism point of view). Health isn't gained you'll say, but that's what armour is for.
There would be no level scaling. We already have different classes of Bandits, Critters and Dragons which provide weaker or stronger challenges anyway.
When it comes to balance, you'd be evenly matched with a Bandit when you start, but a Bandit Chief kills you with 2 hits. (like in my current Master difficulty game...)
Once you're in the later stages you end up slightly stronger than the Bandit Chief but not so much that he isn't a threat at all anymore.
Buffs would have to be decreased and obviously the Perk system would have to be overhauled.
Other ideas that I find would add depth to the game and would like to see, which aren't connected to the levelling system at all:
-Dwemer, Ebony and Daedric armour or weapons are not craftable, but can be improved with the smithing skill and correct resources. So if you find these weapons they are cherished and honed. Daedric equipment being especially rare.
-Disenchanting does not destroy the item. (so basically, if you find an enchanted Ebony Axe, you can change the enchantment)
-Arrow fletching is possible. But Arrows weigh 0.25 (200 arrows weigh 50lbs).
-Fatigue (increasing after 18h without sleep) effects Stamina / Stamina regen
-Hunger effects Health / Health regen
This is just a rough sketch of how what I would improve and once the CS is out I'll see if it's possible to mod. (some things doubtlessly are)
