While similar reasoning ultimately influenced me not to go to law school, tier 1 schools are not overly difficult to get into for someone who has already figured out the game. (A la Paul Graham's infamous essay.)
Frankly, the problems of which the post speaks are really all rooted in the same problem: there are too many people graduating from law school already. The competition allows the firms the luxury of such monotonous work.
Unfortunately, I wanted something else - I wanted to become an expert at some portion of law and exploit my ability to keep many pieces of a situation in my head. However, the opportunity cost, considering the competition, did not seem to match up with the expected reward.
