Why did SE decide to make the three new classes not require base classes?

One of the best arguments for Class removal is the fact that Arcanist is the only class that splits in to two jobs. This is problematic for a number of different reasons which have all been discussed at length in different threads, so I won't bother to detail it here. Changing all the classes into the jobs that they eventually become will mean that SCH and SMN will finally be their own standalone Jobs, meaning they won't be tragically tied together as they are now. The reason your Carbuncle goes away as a SMN is because of the way the Summon spell has to work between the two current Jobs tied to Arcanist, since a Scholar isn't really a Summoner, but an Arcanist actually is. By removing the Classes, Summoner should have more summoning options. The only thing I see happening here that you wouldn't like is either Carbuncle or Garuda being redesigned or removed (To be added again later), since they're pretty much the same pet.
