Hm, new achievement listed for BFA in 8.2 called "Give Me the Biggest Bag You've Got" to collect a list of rare drop items. I wonder if this is them giving into a Timeless Isle 2.0 "Going to Need a Bigger Bag" achievement mindset in full, or if they're only jokingly reminding achievement-oriented players of it, but they intend to make the process of getting all the items far more reasonable. Given how BFA has re-used paragon chests and handled island expeditions, I'm inclined to expect that the designers are going to give into their worst instincts.
