I agree with most everything you said. I feel like because this is their first time doing something open world large scale, as opposed to halo where all they had to do was make the game and then focus on adding things to and adjusting pvp. The campaign was essentially untouched, with the exception of maybe adding modifiers or something later on. I think they didn't realize once they built the infrastructure how much work it was going to be to produce something on the scale of destiny. I am hopeful that they learn from their mistakes while making destiny 2. Some of the things they do however do make it seem pointless ( getting rid of y1 viability of content for rewards, for example, and making y1 weapons obsolete).
