So the Samurai fighter subclass has an ability that lets you get advantage on weapon attacks for one round as a bonus action, and recharges after a long rest. The elven accuracy feat gives you another d20 for making attacks with advantage when using a specific stat to attack with. At level 6 a wood elf fighter could open up with an action surge and use the attack actions to get 4 attacks with 3d20 to roll for hitting, + 10 to hit (20 Dex+Archery Style+Proficiency), doing 1d8+5 per hit. Not the best alpha strike in the world, but it is one that will let action surge shine. Once you get to 8th, sharpshooter makes it drool worthy.
