No Activision didn’t make the patches or content but they set the time frame and so caused bungie to have to take the drip feed approach. Personally I preferred the better quality large occasional dlc’s with cinematic story, because I don’t want to read lore for hours when I’m playing a game, and as long as they were to do regular maintenance patches and events like festivals, IB and Trials in between then I see no reason why it wouldn’t work. As long the base game has the same fun factor that D1 had. It doesn’t work with D2 because the base game feels hollow somehow and doesn’t have the same replayability level, hence the player base drop off.
