Really the only big differences are a) You need to level specs one-by-one here and b) You get very few shared abilities between jobs of one role (compared to specs of one class).
Why shouldn't we compare things that mechanically work the same or highly-similar to other games? Use available data, other games worked these approaches before, we can look at what did and did not work for them.
