Alright, I like some of the points you made.
First, your statement about the progression is definitely something I overlooked. I probably will make the silver/normal craftable at a Tinkerer's Workshop, alongside most pre hardmode arrows (Unholy, Flaming, Wooden, Jester's, Hellfire). I may even make some craftable at a workbench (For that early merchant flaming arrow rush I suppose?) I'll most likely change that right away, thank you for your input.
EDIT: Fast action, I set the pre-hardmode arrows and bullets to the tinkerer's workshop.
Jester's, Hellfire, Flaming, Bone, and Unholy arrows, along with Silver and Meteor bullets. I'll probably change the default ones once I figure out how to change vanilla recipes.
