But what is the advertised core feature exactly? Open world legendaries, story, wizards vault, achievements? IMO there is no single core feature, it’s a collection of things you CAN do.
I finished the story, played the strikes and did some rifts in the process. I still haven’t used a single essence and honestly don’t know for what I should use them.
I’m satisfied with the time I got out of the addon and am looking forward to coming back to single bits of the addon any time in the future.
