The game as designed, requires you to adapt. It is part of what makes the game fun. Maybe you start out as a bow using ranger, but then you get an amazing legendary crossbow, so you switch, etc.
Again, that is what makes the game FUN. As another poster said, you have to sometimes suck up to a mistake you made and carry on.
Too many people don't want an adaptive, roleplaying game. They want a game where they can do what they want when they want.
I agree with many here, and say: use a mod or a game editor, or what for someone to create a god-mode hack that allows you to specify what loot you get from chests. Have fun with that. But stop asking that the game itself be nerfed.
Ummm, no.
Fun is subjective and your definition of genuine complaints as "nerf requests" is again based on, YOUR view, that having to find skill books is part of the fun.
It's not fun to me. It's not fun to other people as well and by posting on this forum, expressing our views, we are providing feedback regarding what is considered fun to us.
Presumably we can agree that most people will not play a game, or even purchase a game, that is not, or promises to be, "fun", yes?
There is no absolute scientific answer to whether having to find a skillbook, or leveling up and returning to a vendor to magically find a new skillbook is fun. It's subjective.
It sounds like you enjoy it as it adds to the challenge for you, which you enjoy. It annoys me to the point of not wanting to play the game and not wishing to purchase a future Larian RPG that insists on this game mechanic.
Both perfectly reasonable perspectives.
