The biggest issues in AF for me are...still the matchmaking and Siva offerings! At least 15 times today I've walked (yes slowly) up the stairs or up for The Warrens and only 3 times have I found anyone in the forge, and then it was just someone waiting for another person with an offering. Those 3 times I had an offering so started an event but never got more than 4 runs in before we were standing around with no more offerings. And no, you can't go and find a Quarantine patrol because either there aren't any or they don't drop an offering anyway (this just happened to me so I don't know what Bungie 'patched'). I really don't understand why Bungie keep creating potentially good events and then make them so difficult to participate in.
