It sounds interesting, and I do like the idea of custom things, but my problem is this favors Archers like me too much. I bought so many weapons to experiment with that it is insanity, yet after Gen 1 I still retired with a little over 100K in the bank. Every Gen I figure I should earn at least that amount considering I have nothing else to buy. I already bought almost every usable bow, ever armor I will ever wear, three bodkins, some useless lower arrows I never use any more, and about two dozen melee weapons I experiment with when I feel amused. I even bought siege shields and three of them to be an amusing support engineer when I am a peasant.
So once I hit the gen you suggest, I should have enough money to take my warbow and turn it into the most ... well... I would be TKed every round by angry people due to me sporting a semi-automatic nuclear missile launcher. I should have well over 1 million when I hit gen 10 or 11, and easy.
It would be nice though to come up with some way to customize a weapon, maybe put a cap on it? Say raise only one thing by two points or whatever?
I don't know, I want more fudge and snuggles... See yah! +1 rep for the interesting thought.
