I assume it is just too hard to accept that the system as it works here makes it reasonable to lose on purpose...
I also didn't do it during the time I was below #250 regularly, as it is rather normal that you try to reach the high fruits! Also this was before relics were introduced.

But now, during Arena event I have a fun defense as always. Even though the reduction to 200 wins for the sweet spot is a huge relief! BTW thanks @ NF for this decision! To me this means that you also have a heart for working people with family, friends, hobbies and other activities that prevent playing 24/7.
