The boxes weren't the problem. It was the amount of boxes and speed in which they were released. First day of new servers there were 2 different p2w events, one of which was a lottery in which the person who spent the most got a DK transfer book, which was 4k usd. The 2nd place person who spent 3.9k got a +7 dragon belt or something like that. P2w boxes last 2 weeks or so, then when those two weeks were over, two new loot boxes were introduced. This happened for 2 straight months. That's why those servers died.
