as others have stated the devs have said on numerous occasions that they aren't interested doing another job split like acn/smn/sch again

I'm also surprised they haven't completely separated them yet because behind the scenes over the last two expansions they changed all of SCH abilities that used to be shared/carried over from acn into "unique" sch only variants

The only ability in the sch kit that is still acn/smn/sch is Resurrection
Even the derpy Physick that acn/smn still have sch has it's own unique version of (which really makes me scratch my head as to why they can't make the acn/smn one scale off of int instead of mind but ehhh)

They also stated in a LiveLetter prior to EW that they had strongly considered removing Resurrection from smn but decided to leave it in for now
that's probably the only thing still tethering the jobs together

Personally I think smn should lose it's low level raise and have it replaced with a raise learned at higher level associated with Phoenix for more cohesive identity
could call it Phoenix Pinion for example
