HW and SB will only unlock during early access of ShB.

By the way, those 100 level 50 quests are a nightmare. They will take a while to get through, and they're the worst in the game. Just remember, it gets better, try not to burn yourself out too much. Watch something on another monitor or TV or something.

The last few start getting better, up till then just spam click through everything if you don't already. These would be the offending ones, and personally I think they should mostly be made optional at this point, it's not doing the game any favors and they're notorious:

Also, I worried about the exp myself, even though I was told not to, and honestly.. yeah just don't worry about it lol. Exp is not what will limit you, it comes easily compared to MSQ progress.
