One of my players noticed that there are no advanced moves for building an archer. Of course, the Ranger gets Called Shot, but it is it.
Yeah, we noticed the same thing (and whined about it to Sage on Twitter!). All kinds of support for blazing a trail through the wilderness, and even for fighting with two weapons, but nothing for the AD&D ranger's (to me) iconic weapon.
The easiest thing to do is adapt the dual-weapon advanced moves, but it's not necessarily the most interesting
option. I like giving arrows the Piercing tag, and Noofy's moves.
I don't really know about making an Archer mini-playbook, though. The Fighter pretty explicitly is melee-only -- notice that his Signature Weapon options specifically exclude bows, or anything that could pass for a bow. What's the alternative? An Archer playbook that comes with a Signature Bow? The Ranger's already the only playbook with any real support for Volley; if it were me, I'd just extend that to make Ranger the Volley playbook as a counterpart to the Fighter instead of making a new archery add-on class. If a non-Ranger character wants to get more into archery, they can multiclass to Ranger, just as a non-Fighter character might multiclass into Fighter to be more effective with Hack and Slash.
(Although even that analogy doesn't hold up that great, because multiple playbooks get advanced moves for Hack and Slash or damage-dealing in melee, but last I checked literally nobody
gets an advanced move for Volley.)
