I think it's fair to say the special summer games loot boxes available for the next three weeks in Overwatch have proved pretty divisive. Personally I can see both sides of the argument. I also happen to have very poor impulse control, so ended up buying 24 of the things in one go.
After opening the first twelve, I began to get the sense I was getting better drops than with the standard boxes, so started capturing from the game for the remaining dozen. You can see the results in the video below.
Now it's entirely possible I just had a decent run of luck, but then I'm pretty certain I got more legendary drops in the course of those 24 boxes than with all the other boxes I've opened thus far, which is easily 60+. Have the numbers been tweaked to make legendary drops more likely for the summer games? Frankly, I'm not sure - I've contacted Blizzard and will update this story as and when I hear back.
