Maybe Blue print categories?
Maybe some system where it was like: *NOTE: (#/#) means number of rares compared to the total, how many you have out of the total amount of rares in that system
Vega Rares (#/#)*
Antares Rares (#/#)
Gemini Rares (#/#)
Mizar Rares (#/#)
Sol Rares (#/#)
Draconis Rares (#/#)
And then you could click the category and it would tell you what ones you DIDN'T have, so you knew what you had to look for.
Then there would be the Regular BP categorys, with the same system.
Also, for a large cryonite fee, you could find out what dropped what. Anybody who posted on the forum what dropped what would have the thread removed. Just for the rares though, since there are Whites
