Balance is what the player makes it be. In Skyrim, the players has a choice with their balances. If they want to be overpowerly, let them. If they want to be underpowerly, let them. Both are possible to do thus there is no need to complain such stuff. If you are complaining then it is because you are making the wrong choices. I, for one, balanced my character out in a way so I can actually die quite easily if I don't pay attention. Also, Bandits in Skyrim can get quite deadly, specially with range and magic.
As for the whole Khajiit things, people mistook it. They don't allow those Khajiit traders into cities. NOT Khajiits in-general. Actually, you can find a few NPC Khajiits in a town or city, if my memory serves me correctly.
Skyrim is lacking some depth but you gotta make sure you list the right ones and not the things you mistook.
"The wrong choices?"
Choosing to level Smithing instead of Speechcraft is no where near the same thing as choosing to move your Rook into a position that clearly exposes your King, nor is it the same as going into a game like Final Fantasy and constantly attacking the Fire Demon, who absorbs Fire as Health, with Fire Spells. That's a "wrong choice." A "wrong choice" in the single player campaign of Mass Effect is shooting at the dead body in the background instead of shooting at the fully healthy Atlas standing right in front of you.
Choosing to level a mechanic given to us in the game should never be a "wrong choice," especially in a game set up like Skyrim,
ever.
If I choose to level Smithing, or Stealth, or Alchemy,
the game should be balanced according to what
I can do. I should not be balancing myself in accordance to what
the game can do. Because then I'm not the one in actual control. I'm not trying to overcome what the game throws at me, I'm making it so that the game has a better chance to overcome
me.
And as far as Khajiits go... they don't allow traders in... yet they never stop to ask if I'm a trader, ever.
