Um, diablo, poe2, borderlands, division2. They all use a similar system to Destiny. As you get stronger you can choose to take on harder content which pits your character up against more enemies, with higher health pools, more armor, more damage, new modifiers and more modifiers per enemy. Effectively making the player weaker against the same enemies. If you want the highest tier gear in all of those you have to engage in the higher tier content. Or you can just,not.
