Hello,
As other posted have noted, it is likely that you simply missed some of the required events from the season interface. If you would like, Leaxer0, please post screenshots of your ENTIRE of your season interface here, and I will go through them to ensure that nothing was missed. If that is the case, I can then go through with you the next steps for compensation.
Thanks!

Alright, I see two points that may explain why Eligos has overtaken you.
1) At this point in the season, you should have been able to get more than 21 GNW battles as long as you have more than two active GNW groups on your server (I do not know your server so cannot check). If your rival has been more diligent about that or if Random GNW counts for these battles, that would explain your lack of points.

2) Your points are correct and there is no error. Your rival simply won zenith.

Alright, so as suspected, this is an issue of you simply not attending GNW enough. Once you attend GNW more your points will increase.
