Now seriously, bodkins are extremely expensive. Remember that the upkeep chance for projectiles is much higher than for any other piece of equipment (not sure about throwing though). That, together with losing 1 in 6 arrows (3 in 8 for normal arrows) more than compensates for the piercing damage. In my archer/shielder with over 100 wpf in both, I lost quite a bit of money with bodkins and gained a lot when I changed them to tatars (without touching any other piece of equipment).
