Sensationalism and hyperbole. How cute.
Why is it? People constantly carp about how everything doesn't meet their personal expectations of exactly what they want. What they are given is a system designed to be as flexible as possible so you can use it (and abuse it) in any way you see fit and then they complain it doesn't force everyone to have the specific game they themselves want.
Half the time you see people saying "how can I level up this skill extra fast" and finding exploits to power grind them, the next minute people are whining their character is overpowered.
It's up to you what you do. That's the whole point. None of my characters are overpowered because I choose to neglect certain areas that would overpower them. It's not difficult. It doesn't take a tremendous act of will. It's not like coming off crack or something. Other people seem to enjoy having a god character that one-hits everything. Hell, there was a recent thread where someone threw their toys out their pram because a bandit killed them.
the whole raison d'etre of the game is it gives you something to play with how you want to play with it. Sure, there are highly debatable balancing issues and the damned level scaling, but creating a huge open world game with a highly flexible character system and balancing it all must not be easy. What they do achieve is giving you the option to play it on your own terms. but then it's like people are saying "The game should be geared to ME and what I WANT". The thing Bethesda do really, really well is not forcing you to have a really hard game or a really easy game and letting you define your character on your own terms with minimal restriction. And it does seem people have a problem with being given that freedom and then moaning about the consequences of their ingame character build decisions.
If you find you're overpowered, don't overpower yourself.
If you find you're underpowered, do some grinding or exploit some of those overpowering options.
