We've uh... been split on the bill for this for a bit. We've been shamelessly waifu2x'ing most of the releases for this, since the available scans are of pretty "eh" quality. However, we noticed that for some reason Uzaki's scans don't take kindly to it [but the others are fine, I guess]. That's a lot more work on the cleaning side. If enough folks don't like the OG quality, we can probably go back to 1.7x sizes and deal with the small imperfections in the long run. Them's the brakes.
