Those who want to avoid PvP can always choose Closed Play (PG/Solo), where they can set their own rules, such as no PvP. Alternatively, they can embrace the challenge and potential danger of Open Play, where common rules apply, including the possibility of PvP.
The point isn't to get rid of PG or Solo, but to prevent Open from becoming another form of PG, where the risk/reward balance is undermined.
This is something UO failed to manage effectively, leading to its long-term decline. Unlike UO, we need to ensure Open remains a meaningful space, not just a diluted version of private play.
