a2r1SC3 is still a safe class to pick, you got A2 for crit rate, Sc3 for split shots. you might want to look around archer thread for some Scout>falc1>mergen , or Scout3 cannon2 or musket2 can also work, your path is kind of versatile, it just depends on where you’d want to focus.
your stat distribution is actually off. the current situation favors DEX heavily. you might want to reconsider this.
