I don't have a gally pretty much the only exotic I don't have, I've completed all end game content with hunger including skolas (just took a bit longer 10 mins extra, maybe more) I never actually encountered the problem of not being invited to fire teams because I didn't have one, if you guys are gonna get all elitist and kick people without one then go right ahead that's your prerogative the rest of us don't actually give a shit, keep tugging each other off guardians...
