Hey Bungie! Great idea for a Ghost Shell. Make an exotic Ghost Shell that does everything! You know, cache finder for ALL planets, Strike exp, Crucible exp, Gambit exp. The Ghost with the most baby! You can even call it "The Old Dude"! It's for old dudes like me that can't remember to switch Ghost Shells every five minutes! IT...WOULD...BE...AWESOME!!! Do it for us old people!
Read your title, and at first thought you wanted and Old Dude voice for the ghost. I immediately thought of a Grandpa Simpson ghost that tells stories that go nowhere as you're playing, and now I want this to happen. But yeah, I like your idea too.
