Infighter vs Gunslinger

Infighters:
Advantages
-VERY high hp, as good as warriors in fact.
-Very decent damage
-Versatile (Like a bandit crossed with a warrior)

Disadvantages
-Crappy Range, worse than fighters and pages, not so sure about bandit tho...

Gunslingers
Advantages
-Very long ranged, better than bowmans and sins
-Can use elemental attacks at 3rd job

Disadvantages
-Crappy damage, worse than assassins.
-Very Expensive Class (bullet are kinda rare, the high level 1s)

Note: Don't judge me too harsly, neva played a pirate before, I've only SEEN how it is played.
