This. Destiny 1 hooked people into playing by rewarding them unpredictably. Didn't know if you'd get that drop in your first raid run, or your 50th. It's how you lay the ground work for addictive behavior as people chase that unpredictable reward. Destiny 2 shows respect for the player. Your rewarded predictably and in an effort dependent fashion. If put lots of hours in, your rewarded well and progress quickly. If you don't you progress slowly. But as you can see, some people prefer the [i]excitement[/i] of a slot machine rather than a steady paycheck. The grinding of The Division and Warframe to Diablo 3s Loot 2.0.
