It's pretty easy to imagine a dev conversation over lunch that would go something like:
"People say they need more to do at end game."
"OK, do these people have any ideas?"
"No, not really. Maybe we should look at previous history."
"There's a lot of love for BC even though there were terrible grinds in that."
"That's a thought. Maybe they weren't as terrible as we thought."
"Well, whatever you do, provide some alternate ways to get to the same place. Just in case."
