Well I m very interested how is possible to loose one defense and land From first, second third place to 50+.. Just like that... Hmmm..
If it was in challenger, I was in 3rd never lost a battle 10 minutes later I was at 74.
Because some people have it timed to an exact science when to hit before reward comes out
You only need to lose one fight, after you are second no one will want to attack you and they'll keep hitting no. 1. That's how you end up last with just 1 loss.
As long as there's someone higher in the ranks than you and they keep getting beaten, you'll fall in the ranks.
