So I'm not sure how anyone else here feels, but I've experienced a large sum of strange coins in my pocket. I decided to buy a drive from Xür and wow do I love it. I bought Stealth (red) and Void (purple) drives for some sparrows and the cosmetics are beautiful. In addition, they speed up rare sparrows which is nice considering, in my opinion, they're a lot better looking than the raid sparrows and add some variety to my game. I was wondering if anyone in the community would agree with me on this point and maybe even ask Bungie if we could get some more Drives in TTK. I would love Pink, Yellow, Orange, White, or maybe even enemy race themed drive as a drop from the new raid. The PvP factions could have themed drives. Who knows. I'm really into the variety of cosmetic options in Destiny and would love the Sparrows to be touched up on. Please and thanks Bungie. TL;DR: I would love to see more than four colors for upgrading rare sparrows or even more rare sparrows to be upgraded.
