Yes you can clearly see they were created with the simplification in mind from the start. Basic and optimal rotations are not so far apart (at least for red mage).
Whereas existing jobs got slapped with the simplification wish, and devs kinda screwed up big time for some of them. Even now with the patches, some still feel clunky and some combat situations are a real pain.

Boss jump in RDM ? Sure, I'll just wait.
Boss jump in DRG or MNK at the wrong time ? Nooooooo mah DPS
