Different skill sets for different jobs. A job being difficult is dependent on one's wanted playstyle and capabilities of performing the best actions.
For example, you called BLM rotation complex, but I find it simple, even easier though now that enochian isn't on a long cooldown. At the same time, I play RDM more poorly, despite being better geared than my RDM, making me do less dps. I found RDM complex to me, even though others would say it's simple.
So plug that in here. Is a job that performs lots of damage at the punishment of cast times your preferred style? If not, it might not be for you.
Also, last note, I do more than 3k dps with the level 50 rotation. Is this a gear issue? I haven't read past this, so apologies if it was stated.
