It will never happen.

Great idea <3

I agree with you.

But then you must take in consideration that, if there's no risk, there's less reward.

You fish out of safe zones, you earn more.

You lifeskill on Arsha, there's a buff there because you're rewarded for taking risks.

You go on a server where you only lifeskill, if this server follows the logic of PA, it should have a debuff or something, to earn less xp and money, since it's safe zone everywhere.

There's nothing rewardeable in not taking risk. It's the purpose of an open pvxvp game. It's the purpose of BDO.

I'm a lifeskiller and I enjoy the risk.

Nevertheless I upvoted your post because I'd like to see how a pure PvE server would work and if, effectively, it would be successful. I don't think so since it would be less rewarding, but I might be wrong, who am I to tell... I know I won't use it.

But I also agree with @Krastonosezs: effectively, it might never happen.

"The PK system needs to be improved. New Adventurers or fearful Adventurers are too scared to play."
Black Desert is an open-world game designed to allow you go anywhere, and let’s you freely enjoy your choice in playstyle. However, the level of freedom goes up, it means other Adventurers are able to interfere in the adventures of others as you stated. But there are a variety of safeguards put in place that don’t compromise the fundamental freedoms of the game.

First of all, there are many safe zones spread around, including towns and cities, the inability to PK characters under level 50, and the growth server Olvia has forced PvP mode turned off. In addition, we created an environment where Adventurers who recklessly PK are imposed with disadvantages that makes it difficult to harass an Adventurer. On the other hand, for adventurers who want to enjoy PK, we are continuing to develop a variety of PVP content, along with the Battle Arena, Red Battlefield, Arena of Arsha, Node War, Conquest War, and the desert itself.

We will continue to think about ways to make your adventures more enjoyable.

This game was designed to have open-world PVP from day one. If that's not the kind of game you're looking for then go play another game as there are plenty out there.
