i drops in glory ranks game

Since it seems most people aren't answering the question, the catalyst only drops if you WIN the match, any match works at any time, was not tied to arc week. Also if you are part of a clan with your flag upgraded it will have a higher chance if you play with clanmates (keep in mind you still need to actually win) aside from that its just random chance.

I got it the week before IB, in normal Quick-play. It requires 300 Crucible Kills to level it up, that is going to take a while...

I just equipped Suros Regime the other day for Iron Banner and found the catalyst on it! Absolutely no idea how long I've had it, or how much time I could have spent working on those 300 kills. Sigh...

Still drops I tried for weeks since the first day bungie put it on the drop table and only got it recently during IB I think I ranked up and reset my valor rank 5 times before I got it (2 during IB) Dont need to have the weapon, I got it while using random weapons. Some people reported getting it after a we run out of medals but I got that a few times and never dropped. For me it just dropped at the end of a game
