I disagree with the power grind part, I think they have made it pointless but you are going in the complete wrong direction, the game is an RPG and there is no quicker way to kill an RPG than to take away the grind. Instead it should be harder than ever to level up, in D1 it was impossible without hours upon hours of dedication to hit max light without raiding, it should take ages to level up. Power shouldn’t be something maxed out in week 2 of a new expansion.
