There are now eleven Legendary skins for the Overwatch Anniversary Event, which is the most there have ever been, and there are no color-swapping duplicates either. buying a crap ton of loot boxes, this created a unique situation I’ve never found myself in before. So, using all these metrics, on average, it will take 27 loot boxes, or 27 hours of play, to get one Legendary event skin. 11 Legendary skins would be 267 boxes/hours, and that’s assuming no duplicates. Given the drop rate of event Legendaries and the amount of hours in the day, even if this is a cosmetic-based event, players are starting to feel the squeeze here.
