A lot of jobs are actually like that. You build up ressources that you burn on some combo or powerful ability.
If you don't like this kind of gameplay, then don't play these jobs.

Regarding your desire to play slashy-slashy with a sword... Damn, that's a great idea. If only Stormblood came with such a job.
