Best Gunslinger build?

Since people are getting ready for the release of pirates (and conveniently a pirate tread) Id thought Id ask whats the best optimized build for a gunslinger.

I know that a Gunslingers main stat is DEX and secondary is STR (like bowmen)

and considering equipments that are available, likely builds are:

Normal build
Dex: high as possible
Str: Just enough to wear pirate gear
equipments
Armor: all armor are scrolled for DEX (hat/cape/shoes/overall/bottoms/face/eye/earring), atk gloves, pendent
Weapon: normal weapon with according str req.

Low-STR build
Dex: high as possible
Str: low as possible but not 4
Armor: all armor are scrolled for STR (top/overall/cape) and Dex for the rest (bottom/face/eye/shoes/hat/earring) atk glove, pendent
Weapon: normal weapon with according str req. (limited)

Pure Dex/Strless build
Dex high as possible
Str: 4
Armor: all armor are scrolled for DEX (using sauna,FS,SS, Etc) (hat/cape/shoes/overall/bottoms/face/eye/earring), atk gloves, pendent
Weapon: a Gun that doesnt require STR (maple weapons, gacha)
(no pirate maple weapons are available as of now)


out of the above 3, which would be the most optimized build?
