If there ever will be such a server, everybody who types "duel for spot?" should be automatically send to the pve server. 

Lol.  How do you know this and why would you care?  If they are on the pve only servers, presumably you won't be there, so why does it matter?  Don't force your playstyle on everyone else.  "Evil!"  lool.

On a side note, I came across a reddit post that made me smile as it was soooooo ironic.

When we said that creating a regular pure pve server would then create the need for additional tweaks, dedicated ressources, and would allow new desires from players, we've been told that it was easy to make and maintain such a server, a simple switch. 

Some here are taking New World as a reference, so these are the words of a dev (post 336) :

https://steamcommunity.com/app/1063730/discussions/0/3060744478184211321/?ctp=23#c3055115411898940511

We don't have plans for dedicated PvP servers at launch. The main issue is dividing dev and support requirements between slightly different versions of the game. Then we'd have to be really clear about what long term support would look like, since those PvP server players would expect game updates targeting their version of the game too but mapping to their top needs and wants, separate from how the majority of other players were playing NW.

Making a pvp setting in New World would look like a "simple switch", the removal of the pvp flag activation, still it would divide devs, for slightly different versions of the game, it would imply a reflexion about long term support and so on.

Creating a regular pure pve setting seems easy on BDO? Well, check what it means from a dev point of view.

And yes, again, we were right. 

I can see it now:

"For 10,000 Pearls you can rent a private server for you and 10 of your friends for 14 days!"

Seems like a nice idea.

In reality, terible idea...

Less P2W than cron melting.

This.  Players often fail to see things from the dev point of view, hell, even from a big-picture point of view.  All of these PvE only server requests are rooted in "I don't want PvP therefore don't make me PvP".  As if the world ends at any one person's ideologies and preferences.  HA!

10,000 Pearls for one week private server.  Up to 10 friends.  You can have the entire game to yourself, for $100 a week.  Seems fair.  While the rest of us, who play BDO as BDO, and not some convoluted version of Diablo or PoE will remain in the PvX setting BDO was founded upon.

One excerpt from an interesting article I found that PVE Only requests in BDO make me think of:

Site:  Players Like To Optimize The Fun Out Of A Game (thegamer.com) https://www.thegamer.com/players-optimize-fun-out-of-games/

Artle name:  "Annoyingly, Players Like to Optimize the Fun Out of a Game"

Exceprt:  "This generic example entails the concept of risk-taking. The great thing about taking risks is that - although they imply a chance of loss - they can often lead to a greater sense of triumph if the risk bears reward. However, if given the chance, players can find themselves gravitating, consciously or otherwise, towards a safer route that will guarantee success, even if said route is comparatively unexciting."

And this, folks, brings us to PvE only server request in BDO.  I get it, PvP can be a nuisance.  A player-killer will prevent you from grinding in peace and accumulating resources - resources in which you need to progress in the game.  The existence of player-killers (rare in my experience, but whatever) is an inherent "risk" when it comes to accumulating resources via monster grinding.  The "risk" of losing time, and thus, losing potential progress, due to PvP encounters.

PvE server aims to remove that "risk" altogther.  I vote a resounding No.  Why?  Because I care more about the game as a whole, than I do any individual player's preferences.  Even mine.  

Here are more excerpts.

- Basically, why go for the risky route if there’s a safer one that promises a greater chance of survival anyway?  Well, because it's boring.

- Basically, if there's even the slightest chance of an easy way out of a given game sequence, many players will latch onto that and milk it for all it's worth. Doing so can mean that a lot of the cool stuff intended by the developers doesn't get to be experienced, and that's sad AF.

- So how can designers avoid this? A few subtle tweaks can make all the difference. The answer lies in the concept of reward to encourage specific playing styles that entail more risks. In other words, reward players for taking risks.

- In essence, designers should take precautions that encourage players to have a more enjoyable gaming experience, and that save gamers from their very boring selves.

No need to make BDO more boring.  We already have a lack of "fun" stuff. you know, things where you don't worry about silver per hour, or getting that rare drop.  Things where we can instantly Q up with a group of friends and just have a blast - no silver reward needed, the FUN itself is the reward.  Things like that.  We have little to no "fun" content like that, everything we have is silver per hour based, or efficiency based.  RBF is the closest thing we have.  ONE CONTENT IN LIKE 5 YEARS.  We need BDO to be more "fun".  Not more boring.  A risk-less PvE only server is just that ---- BORING!!!!!!

My suggestion and hope is that once electing to play on pve servers you are locked to pve servers. No jumping back and forth between normal and pve.
