Bonus stats are pointless

[L-D-Omlette]

So my question now, given how simplistic this system is why is the bonus stat points even allowed in the game? It only allows for people to risk wasting them in stats that serve little to absolutely no purpose, or even more importantly for classes like ACN that have 2 jobs, it forces the player to pick only 1 build (play SCH better or play SMN better), or to split their points in half and only play each at less than their full potential. This is a concern for those that like to play both SMN and SCH, and for all future classes that will get 2 jobs.

You answered your own question...

The idea is that when you advance a class to a job you either specialize in one or the other, or try to balance the two. At present ACN is the only class with two jobs, but when more jobs are added to each class this will become more apparent. This is your decision tree.
