You know, at this point, they should just scrap all the other "currencies" like Exploration and Diplomacy and everything and just make it ALL emblems. The preponderance of overlapping and redundant currencies is just crushing. All the items are level locked so introducing level-locked currency is not only redundant but limits the game in unnecessary ways. You can't just go explore a nebula here or there you have to explore THIS nebula and ONLY this nebula if you want to get the level-locked currency to buy your level-locked item.
Make EVERYTHING into emblems and then have emblems be the only non-EC currency. Leave EC and Latinum for their primary uses but scrap everything else...its just too tedious. And then you won't have the game limited to 5000 people trying to scrounge for tidbits in B'Tran.
