Looking over the rules in for crafting, it seems utterly and completely pointless for PC's while for NPC's it makes sense. Let's just compare vs a caster: (This is profit/savings, excluding raw materials)
Caster Level, per Day, per Week, per Year, Item Creation details
1, 12g 5s, 87g 5s, 4,450g, Scroll 1x1x25
2, 25g, 175g, 9,100g, Scroll 2x1x25
3, 150g, 1,050g, 54,600g, Potion 3x2x50
4, 200g, 1,400g, 72,800g, Potion 4x2x50
5, 1000g, 7,000g, 364,000g, Arms&Armor 1x1x2000
While creating mundane items is a fixed 1 Silver a week.... regardless.... This means taking any crafting skill is utterly useless overall, not only because you can't make a reasonable profit, but it takes forever to make ANYTHING worthwhile (Making 50 arrows takes 24 days, geez, if my math is backwards then it takes 10 weeks instead!!)
I've written a potential creation feat and alternate rules that exponentially increases the amount you can do in a given week (from 1 Silver to 25, to 600, to 15000); meaning if you take the feat once you can make 50 arrows in 1 day (or 3 if my math was using the wrong numbers); To get anywhere near what the mages can make you'd have to use at least 2-3 feats.
Thoughts anyone?
