I totally agree with this.
In my case, I have been here for 10 years, I have become a Top Rated Seller with thousands of positive reviews and since they launched the new system, my new Level is 0.
In just one day, apparently I went from being one of the best sellers on the site to the same level as someone who is just starting out or worse.
The funny thing is that no matter how well I do my job, this score does not update. As I understand it, this value is updated daily but it has not moved a bit since day one.
I just hope they know what they're doing.
