I suggest you try changing to SMN. It is a typical debuff class, but still much harder to play than BLM.

About crafting, have you tried to "Quick Synth"? Not worth it, but if it's the materials you want, you don't have to synth them one by one.

As for dungeons... I'd love a "the Aurum Vale (even harder)", but people would just go over geared and call it easy, like they already do with AK and WP.
