How do you like to play? Dex/Faith works well for me, but your playstyle may be different.
I like having options. Have always enjoyed spellsword type classes, having melee for the bulk of my combat and magic covering ranged and buff/debuff. Usually enjoy quicker weapons but I've enjoyed using great swords since they eat through poise. Hard to nail down what my playstyle is exactly besides versatility.
Faith+1I understood that reference
Arcane isn't very useful tbh. Hell I'm not even sure why it's a stat.
