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

Most player never get to try any endgame stuff. We cleared Coil 1 and Coil 2 in an planned PF group. No one was held back and it was really easy with a Bard in the party make up. You dont really need two Bards. Point being is " I Did it!" Classes could just going on to become their own jobs. I hate Bard. I love Archer. wouldnt be nice if Archer was it its own JOB, made with endgame in mind? More jobs = more FUN = more choices for endgame groups to make. Also, it makes for bad story telling for a Lv 1 Bard to "Just" know how to use a bow. It makes for great story telling for a Archer to learn how to use a Harp. I still hate ALL Endgame stuff.
