Wasn't SB supposed to rework and simplify the whole "having to be level X with your job unlocked to have access to most of your abilities to be able to fully enjoy your class"?

If I take my THM as an example: depending on the situation I literally only have to press a few buttons consisting of fire, blizzard, transpose and thunder.

I was hoping the class will get better once I've unlocked my job so I forced myself to get to lvl 30 - but no: even having BLM unlocked I still have the same boring abilities while almost being forced to get to lvl 70 to fully unlock all my abilities to have a real shot at actually testing the class in its entirety to see if it suits me or not.
