1, 2, 3 combos are just unnecessary bloat, there's no thought process to them and doesn't really add complexity. Bard is far more complex with having Burst Shot to hit multiple times, but it makes you pay attention because it might trigger the ability to use Refulgent Arrow. If I was to list the most engaging jobs, it would be Red Mage, Dancer, and Bard because they use RNG procs instead of just hitting the same string of buttons the entire fight.

I don't really care if the NPC quests are made more complex because you only do them once and then never again, so why make it more complicated than it is?
