Hi,
I believe you're referring to Prism, one of the game designers for Nostale.
Regarding your concern about the possibility of the game being influenced by only a few players on Discord, I want to reassure you that the SP balance changes are based on feedback from a wide variety of sources. There are multiple game designers involved, along with several testers and feedback from the entire Game team.
Before anything is finalized, it needs to go through an approval process, so there are many people reviewing and contributing to the decisions.
For example, if Archer’s SP2 isn’t viable in PvE, and only a small number of players use it in PvP, it makes sense to consider changes to improve balance. It’s much easier for Gameforge to make adjustments to SP abilities themselves, rather than waiting for changes to come from Entwell, the developer.
As for the "leaks," the screenshots shared by Prism are likely already approved and a finalized version of the changes. They're likely just sharing these images for fun and interaction. There will be a full overview of the changes when they’re ready.
