Same here - no catalysts yet. Even went through and checked every single exotic weapon to make sure it didn't drop without me noticing. I am having flashbacks to the Husk of the Pit bug that Bungie refused to investigate at first, insisting it was just RNG. At least some catalysts are dropping for a lot of people UPDATE: My first winning Crucible game after posting this, I got the catalyst for Vigilance Wing. Probably a coincidence, but in case it was divine intervention (i.e. nice Bungie employee) - thank you!
