I think Bungie doesn't know how to run this kind of game with a balance of grind, casual, hardcore, team, solo, pvp and pve. Their only previous large game experience was halo which had a much smaller focus. Really no games offer the balance of PVE and pvp destiny attempts to. They are still struggling to figure it out. They keep mixing up the formula trying to find exactly what works. I've accepted for awhile destiny is a beta for this new kind of game and we can hope destiny 2 will be better. It's still enjoyable and a good mix of gameplay just not perfect.
