Been so interested in this! I'm not sure I care about the printing fading but would you say the rest of the keycap feel low quality? Is it real thin and flimsy?
To be honest, they don't feel terrible to me. If I hold a WASD keycap next to one of my PBT keycaps, I can clearly see that the PBT one is ~1.75% thicker. But when I'm typing on them, I really don't notice much difference. They don't really sound any different. The only thing is that the WASD caps are a bit smoother feeling, as ABS tends to be.
WASD also offers the option to buy single keycaps with your own design printed on them. So, depending what you're going for, you could just get a few novelties or modifiers with whatever you want, and then combine that with a higher quality set.
