it really all depends on what you play the game for. if u play to simulate killing things, then blind levelling up is good. more importantly, it depends on how you want to go through the story. some people (like me, sometimes) prefer to get to an uber-high level so we can take as much as we can from the storyline without having to worry about dying. others prefer the challenge of having to level up naturally, as the game progresses, and focus more on an equilibrium between storyline and gameplay.
