We're excited for the return of year one exotic weapons. There's a limited amount of new year two exotics. The Strike Playlists have been reduced (depending on difficulty) and some existing strikes have just been retuned. As soon as one weapon starts to dominate in the crucible that weapon is nerfed (easier to address one weapon than buff multiple alternatives). Obvious features such as faction sparrows have not been introduced. Year one items often outclass year two counterparts. Previous random events (Wolves) have been removed. Two raids are obsolete. Time gating introduced even more. Off the top of my head I think the developers have already given up.
