This is true, and is fine, but proper scheduling goes a long way to make the game SEEM like there is more to do than with bad scheduling. How many people have you seen that say "I don't have anything to do" despite having jobs at ~30? Having jobs release separately keeps the hype going, and makes patches feel more exciting. I know when the expansion released I was only excited about DRK and that completely overshadowed the other two, perhaps if we were getting AST or MCH in 3.3 I would have paid more attention.
