Yea, I’m confident this is not ONLY a sync error between client and server. It’s definitely an issue with how they programmed the algorithm to determine PvP point value to address the original issue.
There are most certainly issues with the server syncing, lol. BUT, this issue is not the same. The DP will change for both the base owner and attackers, and it’s been left for quite some time without any affect to PvP point value. Alternately, if you change the perch the PvP point value changes almost instantly.
