I got mine in less than 20 runs. I really wish they would come with a unique perk or something. Oh well. At least they look cool. I'm still trying to get the freaking Imago Loop. My buddy got his first one the very first day of TTK and it dropped with outlaw and firefly. He has gotten 4 more to drop for him (with different perks) but I have yet to have a single one drop for me this whole time. And just to add to my frustration, I have been grinding crucible for weeks now trying to get the Eyasluna but with no luck. That same friend (who only plays pvp when it's the daily) joined me for a daily skirmish and he got one. Some guys have all the luck, and others just get shafted by RNG.
