Very informative. I wasn't (un)lucky enough to get all 5. I have three on my hunter, one on my Titan and two on my warlock. If this turns out to be a bad thing when rise of iron drops in a few hours, I'll be happy my Titan only has one. I had, however, a theory relating the colors of the "mites" to corresponding engrams and the ability/inability to decrypt them based on which infections you have come launch time. That would suck. I mean I assume there would eventually be a cure, but this would make all the hoarding pretty frustrating for many.
