Got the Legendary Sparrow you can get by per-ordering the expansions, and I can't use the drives on it. Apparently rare Sparrows are better then legendarys... So that's stupid. *claps*
Edit: So I think there should be a way to upgrade legendary sparrows to an exotic status. You can upgrade rares, so why can't you upgrade legendarys?

lmao the plasma drives are used to make a sparrow legendary, not to make a legendary sparrow better.
