It's because of the new loot system. You do normal raid twice then get all gear for 32. You beat hard mode twice get all primary raid weapon. People don't find any interest doing raid anymore. I miss VoG loot system. You actually have to grind and work hard to get gear and weapon. I mean I wasn't lvl 30 until I started playing HM VoG. I didn't get Atheon epilogue until TDB released. Because I was missing AE I was playing every reset Of VoG. Then I stopped playing ng VoG. I have every single exotics including weapons and gear. I was still playing Destiny until Bloodborne released. I will go back when HoW released. I still love Destiny and I wish they bring back the VoG loot systems.
