What you find fun is subjective. Some people like complicated jobs and being able to perform their mechanics in any situation. Like NIN, MNK, DRG, etc. Others prefer simpler mechanics that they don't need to think as much about so they can concentrate more on the specific encounter, like BRD or BLM.

Try MNK I guess. It's got high DPS and while the situational requirements can be a pain, probably is easier to deal with than mudras.
