Just a quick gunslinger question

OK, bad comparation. My point is 10 consecutive burst of elemental damage in less than 1 second without cast time and almost no delay is way too powerful. I can't say much about holy since it's natural to make weapons out of that material, silver. You should notice that those bullets are very costly and heavy.
Still, you can grind anywhere with plain or silver arrows/bullets. You can still hurt them, despite having lower damage. They will die eventually. How do you think players started out? Archers can only have 2 additional elements until they got to job level 35 and learn arrow craft that uses their stuff to make weapons. Other classes starts with neutral weapons. Did that stop them from leveling? No, slower but they can still level. Also, you have range way further than archers. That's a plus.

Having elements does make things easier, but they are not a must. If you really need them, use converters or buy an endow from full support sages.
