Idea:

What if we had the same world as what we have now except everything there would be an outlaw. It would be reminicent to Ultima Online (Early 2000s) where you could use portals that were scattered around the world to enter / leave this gloomy dimension, full of outlaws, no laws, open PVP including in towns, no penalties for killing and there would be a good reason why you would want to travel there as a blue character but also good reasons as a red player.

The enemies would be hard, maybe Arsha hard, maybe harder? There would be quests and exclusive items that you can obtain there. The cities would look broken down and the music would be fitting.

I don't know, this is just an idea and maybe you guys have better / other suggestions to add to this. It would double the world size and really get people excited to play PvPvE. I don't know if any other game did this other than UO but I'd be ready to play this... As a witch or wizard, not a shai lmao.

Basicaly Arsha without broken cityes, quests and exclusive items that you can obtain there. Im all for it, but not like extra server. Something like a zone, a new continent, to keep the world in one peace. A good idea, but need to be considered the gear diference and how many spots would be valuable. A place where you can party up to deal with stronger players to obtain rewards.

In a way, isn't that something Elvia can lead us to in the future?

I seem to remember devs announcing a new way to go on Elvia realm, which would be accessible from any channel. But anyway, if we end up with full Elvia realms, we may end up with a destroyed world? 

I'm not sure, I haven't heard of this but it sounds like it would be a great addition. I would love to see a destroyed, creepy world that puts us on edge wherever we go. It might be nostalgia talking but it was scary AF to go near the portals in UO because a red player or a group of red players could just suddenly appear from there and start attacking you. Being a full-drop PvPvE game, it was genuinely an addrenaline rushing experience especially when you go visit that dimension for yourself. The fact that the game had super high latency didn't help things either, you think you were getting away but then you would get immediately teleported backwards, stuck because the other player paralyzed you. It's nightmare fuel just remember it haha.

There were also other portals that sent you to the underworld, which was different. It was I think purple in theme (color tone) while the evil zone was red and dark but parallel to the real world except destroyed. The underworld was where the monsters came from but wasn't a parallel world but a completely different zone entirely like going to hell. I think BDO's equivalent to this is Hystria and other places like it.

As far as quests, and features go... I'm not entirely sure what they could do to make it enticing. Maybe weapons and armor that get stronger depending on the souls you collect through it, and it creates sort of a PvP enhancement but in the blue world, you get the same thing but for PvE? I don't know, there could be reasons, thus this thread! :P

What we need in BDO currently is raids! lots of raids with very good rewards and raids can be done only once per day! 

Raids for hardcore raiders (solo & group) with stories!

Then we need lots of dungeons with an awasome action cnematic story telling! and good rewards!

New Mounts beside just horse!
Bring Shadow Arena back to BDO, that same Shadow Arena where enemy player's HP bars was invisible. 
Buffed rewards of other released contents such as Alter of Blood and other more...

Old Dark Rift bosses where rift boss summons their minions! 
End of Seasons! because of seasons gears, old content green gears and ultimate green gears are basically useless! 
FPS drop issues fix!!

graphic changes in old modes. Very Low - Low - medium - High. Make this graphics better by adding and removing high FPS drop animations! 
PA listen! 80% of BDO hardcore players don't even play in remastared mode or other very high mode cause of FPS issues. Your design of Remastared mode will always be better but what will there be remaining if players are playing is potato-graphics? that all blured out graphic setting. 
I don't care if BDO graphics are of art style like Guild Wars 2 or cartoon style like WoW & FFXIIV, just make it better! 

One thing is it needs to try to follow some story telling,

started playing like 1 year and half ago so dont know much lore.

What ive been thnking is that now that elvia has infested calpheon, the next regions have to follow allongside upcoming shoes/gloves ''fallen god'' releases, and after all of them are infested we start getting illezra's trials, along with a tower system and release of main/awak ''Fallen god''.

Once you pass this tests and climb the tower system Illezra lets you enter Hadum/Elvia Realm.

Now hadum/elvia realm is where the true Black Desert lies, called black desert not because of the immense amount of black sand but rather because in this dimension similar to where our adventure starts there is no kept cities/npc safe zones, every zone even cities are barren land turned into ashes with nothing else but old bricks and burned out vegetation.

The monsters in this zones are not your typical grind spots to circle hours on end, one might think so once informed about the 320ap minimum, but once the adventurer tries to fight this beings he realizes, that their hp and defensive capabilities are beyond the power of ths individual thus the need of Party/Platoon.

Non of these spots are soloable, Minimum is 3 player party and goes up to full platoon (MMORPG when?) 

The types of monsters can vary from High Dark Elves, Giant Ancient Sentinels, Khalks to Demons and Dragons.

Lore kinda.

This is a glimpse of what our world would have looked like if it wasnt for the intervention of Illezra, who split her power to create 2 Dimensions, one where beings bestowed with power have a chance to gain knowledge and fight back the invasion, leaving her consciousness to guide adventurers and slipping a small portion of hadums corruption to train them for the Other side.

The other half of her power toegether with its body sits in Hadums Realm, this body was left but with only one rule, to close any kind of portals leading to our world.

But as time goes forward Illezra grows weaker and Hadums realm stronger, and this is how each time we get an new elvia zone.

The trials we should get on the tower will be summoned with her last bit of power.

This opens large scale pve and even Guild vs Monster hoards  kinda content, imagine a guild building a castle and at certain times in the week hoards of monsters try to come in to attack flag or destroy everything, sounds fun to me.

Well this is my opinion on what might come ahead.

^ That sounds pretty cool actually.
