This is the thing that confuses me about relating it to difficulty:
Step 1 - play game on Adept, ok but could be harder.
Step 2 - raise difficulty to Master, now game is too hard.
Step 3 - use smithing/enchanting to get the best gear in-game, now game is ok but could be harder
Why even have step 2 and 3 in that scenario?
Also, it's somewhat frustrating that people associate using the CK with making everything God-like, does everything have to be taken to the extreme? Is it that hard to imagine that someone would use it to create items roughly equivalent to things you could use in-game mechanics to make? Is it hard to imagine that to get those items it may take a quest or other such interesting achievement other than standing in front of a forge for hours?
That's the beauty of Skyrim. You can make it as challenging as you want it to be; it just takes some self-restraint.
Really, I wish they had put some stuff in the game that is better than stuff you could make by yourself. It does seem silly that after several hours I can make something that's more powerful than anything else in the game, but whatever.
If crafted gear wasn't superior to quest reward gear, there'd be little point in crafting beyond RP.
If the game is too easy, change the difficulty setting. If it's too hard without crafted gear, then craft your gear. If crafting is a boring grind for you, then use the console to level it instantly. If you resent having to "waste" perk points on crafting, then address it via the console.
I don't see why you need the CK to fix your "problem", unless creating some set of unique uber-gear that drops off Alduin is the only way you could possibly enjoy the game.
