There’s actually a decent bit of discussion on all of this in the Feedback on Combat. Additionally, some of the community’s suggestions on Archer-related classes can also be found in the Class Suggestions thread.
Personally, I wouldn’t mind an archer “craftsman” in the future, but I don’t feel the early game needs this (or can support it). Essentially, this hypothetical unit would be on par with the Blacksmith as seen with melee units, and considering ranged units can be so powerful and versatile in the game, I can see justification for having a unique class that is required for tapping into that particular branch of combat.
As I’ve argued for every other crafter we currently have (besides the Carpenter, who already meets these points a little too well), they need lots of recipes and purposes to keep them practical and justifiable. Additionally, having more recipes that require multi-class cooperation will make them feel more connected to the town’s community (unlike the Mason, which is currently in its own little world…).
