The way I see it, it sounds like this is a serious strategic error.
I don't actually play Destiny, not yet anyway. I've wanted to try it for some time, but the supply problems have left me unable to do so. I do, however, play Star Wars LCG, Netrunner, and Lord of the Rings, and I used to play Magic, Yu-Gi-Oh, and Pokemon.
It seems to me like FFG just doesn't get how you maintain supply for a TCG. The big three I mentioned above -- Magic, YGO, and Pokemon -- all have multiple print runs for their sets. Some sets, like Magic Core Sets, are repeatedly printed until a certain period of time has elapsed. Others might just get a certain predetermined number of runs. But they all get multiple print runs, with the intention of maintaining supply for a few months or so for each set. That requires a rather rapid supply chain. I don't know the details on the supply chain for all of them, but I do know that Magic cards for the US market are printed by Carta Mundi USA in Dallas, TX, not, you know, China. Carta Mundi is an international company, so they have printers elsewhere in the world that Wizards uses to print for those markets too. It's a lot easier to adjust to demand when you're printing domestically.
If Fantasy Flight could move printing out of China -- which they probably can't afford to do -- they could develop the infrastructure needed to support a TCG's demand. They can't, so they're just sort of stuck. If they did, we'd probably see a drop in production quality and/or a rise in prices.
