YOU say that playing the game normally will end up with a broken, OP character. I have not had that experience.
I have 4 characters currently. 2 of them are pretty OP, the other 2 aren't at all- they're quite challenging. The difference is that on the OP characters, I conciously chose to do things that I KNEW would make them OP. Not only that, but I kept at it, and improved on them, so that now one is so OP, I went through a dungeon that had not just a Draugr Deathlord here and there, but more than 50% of the Draugr were Deathlords. I only had to use potions twice I think. Many of them went down in one shot, and never more than 3 shots. My health rarely went below 80%.
The other 2 are extremely challenging, requiring multiple reloads on almost all boss fights, and not uncommonly on just regular fights with more than 2 enemies.
The difference is that I just play and level those two characters how I feel the character would act- i.e. I role-play them. I don't purposefully avoid certain skills, and in fact, all of them hacve done some crafting. I just haven't power-leveled crafting (or any other skill) on the 2 challenging characters. One of those just getting to where it's easier (not OP, but I don't die every boss fight any more), and it's in the high 40s. I suspect it will be OP by the time it passes 50, but that's to be expected. There's nothing in the game that's as high-level as you once you get past 50.
