The temper scrolls are irrelevant. I get locked out of story, lore, and cosmetics amongst other things that I paid for. And the saddest fact is that there has been an uproar about forced grouping being added since before D4 released. So much so that they promised that there would never be any content that required a group to do.
So not only did I pay for content that is in the game, I don’t get to play it even though I paid for it. And I was lied to before release.
Blizzard must reverse this and add a solo option. I don’t care if it take me 3 times as much grinding to get the rewards out of it, at least I could get them. Exclusive content for a very small minority of D4 players is wrong and goes against the spirit of what Diablo has been for the last 2 decades.
