Jobs that start at a higher level are not designed towards newcomers.
There's a reason you need a character to have reached Ishgard for the HW jobs and a level 50+/ 60+ char for the SB/ ShB jobs.

Dancer is designed to alternate between a fairly calm build up phase and a busy phase and their CDs line up nicely with raid buffs. Smoothing the busy phase over or making optimal Flourish use easier is like making Leylines portable. These are core challenges players will need to overcome if they want to optimize. Not every class design is for everyone but that doesn't make it inherently bad.
