Yes, this arena system is very very *. I myself have been digging my way up from -17 points when I realized there actually are good rewards.

Sadly, as far as I am aware this system comes directly from Chinese server, and unless it was changed there, nothing will be done about it. And if it was changed on CN server, we will still have to wait until English version actually gets to that point.

(That being said, I myself gave up on trying to reach 6th path rank, even as good as these rewards are, it's just too annoying.)
