Really well written piece! I'm also curious about the future of lootboxes. The Battlefront 2 backlash caused such a stir that I could easily see some type of regulation instituted.

When it comes to Blizzard I personally don't have any issue with the way lootboxes in Overwatch are implemented, because they are purely tied to cosmetics and not progression. On the other hand, in Hearthstone the card packs function like loot boxes and are %100 necessary in order to be competitive. It would be interesting if this system had to be reworked, and I'm sure consumers would probably prefer paying directly for the cards they want.
