When lootboxes were introduced, there was a statement, that lootboxes can contain everything from previous seasons except Battle Pass items. So, Shop skins, legacy content, limited-time event content.
As I was collecting things over the years, I found myself in the duplicate situation fairly quickly after I’ve acquired several items from Reaper Dusk event that I missed and few items from first Mischief & Magic event. As an experiment, during that lootbox introduction season, I didn’t buy the bundle with Toxic Bastion/Winston skins just to see if this system works next season.
Next season started; I earned my first lootboxes. And I was quite surprised that the season 15 shop content was not included in season 16 lootboxes. I continued to open lootboxes just to see duplicates.
The question is: when shop/event content from season 15+ will be added to the lootbox drop pool?
Just curious, not trying to complete my collection anymore, missed quite a lot of Twitch drop stuff etc.
