I have a fighter with really high rolls, 18 strength, 17 dexterity, 17 constitution. I'll eventually be getting 18 in all three of those, I'm currently level 4. I have a warhammer and a heavy crossbow. I have the crossbow expert feat (ignore loading, melee disadvantage). I intend on fighting with a warhammer and shield in melee and my heavy crossbow at range.
Archery will be giving me a +2 on ranged attack rolls, while dueling is a +2 on melee damage rolls. Which of those is more valuable?
