Back while Destiny 1 was winding down, we were told by Bungie/Activision that the main complaint was lack of content being released in a timely manner and so they would have other studios help with Destiny 2.
Fast forward to Destiny 2, and we have the exact same content release schedule as Destiny, even with a separate studio helping with Warmind.
Destiny 1:
Base release: Sept 2014
Dark Below: December 2014
House of Wolves: May 2015
Taken King: Sept 2015
Destiny 2:
Base release: Sept 2017
Curse of Osiris: December 2017
Warmind: May 2018
Forsaken: Sept 2018
So where is the extra content that was supposed to be delivered? If Bungie/Activision's definition of content is events like Faction Rally/Iron Banner/Dawning, that is not what players consider content. Campaign w/cutscenes, new strikes, real raids (not lairs), Prison of Elders/Court of Oryx.. those are real content examples.
Add the fact Destiny 1 had Iron banner and seasonal events as well, so what's the difference? This is the exact same schedule as Destiny 1 even though we were promised quicker releases of true expansions..
