Already done, son. Did quite well. Gonna have to do more than throw misunderstood economic buzzwords around to get your pyramid scheme off the ground. You only propose this idea because you're too lazy to gather and want a system that makes you competitive again. When you can mash together all the trash that you make and make the best bow with it, you don't have to have any quality as a crafter whatsoever. All you have to have is skills that play to your talents. Mindless grinding and bubble riding.
Within two months your ancient crab bows will be junk too because of overproduction. With no real rate-limiting step you're only stalling the problem so you can make more money off it like you did in October "when the economy was good." You mean when the economy played to players like you who rode bubbles. Now you're a common R50 with no HQ support. No wonder you think the economy is bad now.
Hypocritical of you to not want the HQ conversion rates touched (because you don't have any) and yet want to be able to make Crab Bows +4 out of all the spam trash you have lying around. Gee, that's not going to make HQ weapons easy when any lazy crafter can just spam their way to HQ+4 with NQ products they find lying around town.
