So i made a pirate gunslinger with full dex, and it didnt work out really well. So i went back to adding strength to my build. I was level 25 still doing 25 damage to the crocks in the KPQ. Any advice?
Gunslingers won't be outputting decent damage until you're 4th job unfortunately. If you want a slight boost in damage, stick with adding Dex instead of Str, as that's what increases a gunslinger's damage. At level 35 you can get a maple gun which will boost your damage (not drastically). So basically, just stay str-less until later levels (at least until after 3rd job) and keep adding full Dex to maximize your damage, making training slightly easier. Use maple weapons as you go (levels 35, 43, 64, 77). Afterwards, you can start adding more str so you can wear either a concerto or dragon revolver.
