TES games the classless system is considered a selling point. Some don't like being able to do anything they want.

Lack of imagination and creativity in Millennials.
I can start with a Fighter and buy traits & skills, make it a Rogue & retain my fighter specs..
OR Dual Class. Though I like the "skill by use" leveling of skills, there should be things you were not taught to do, so if Skyrim put lockpicking behind a Level up point spent, when you choose fighter, I'd be ok with that. But not everything open off the start, and mage requiring say 3 different skills bought before you can use spells, if you didn't start as a mage.

I'm getting the impression that maybe this isn't the game for you?

All games are for ME ;-p. (A bit of lying there.)
But I don't have to like everything about any game.
