I think everyone needs to take a step back and breath. It's not like the Devs gave us a detailed explanation of what changes about each job. We only got a overview on roles and a brief overview on each job. March 29th well give a better idea on what each job plays like and what changes happened.

As for making a job simpler, that means a hundred different things to SE. Stormblood made jobs simpler. For BRD they might have just made the song proc passive rather than related to DoT. They could have just extended the duration of Straight Shot Crit buff to 45s. They could have changed Army Peon to apply Raging Strikes buff for 5s on proc. We just don't know.
