You can control multiple servers at once if you stack the war times correctly! … 
Unfortunately this is something that happens. Some players are playing in wars on multiple servers and some of the mega companies will stack their war times in a way to let people keep EF/WW on multiple servers if they wanted.
Once you are 625 in all your PvP and PvE builds, 595-600 on all the crafting you desire, have good gear for all the builds you enjoy playing, the only thing left to do is the social/political Territory based PvP, crafting (daily CDs) and M10s If you have two fully geared players on two different servers, you can do all that doubly by doing it on the other server as well.
Really, is that your point? There are 90% population in NW never have chance to war regularly
There’s a million reasons why someone would run multiple characters.
Perhaps a Streamer has 1 character for strictly streaming, but plays with friends on another character.
Maybe 1 character is to play male, and 1 to play female.
Maybe 1 character is for playing with 1 group of friends and another is for playing with a second group of friends.
Maybe 1 character is for serious government business and the other is for fun and trolling.
So many reasons.
This makes sense only if I have done with my main character , either wait for new content or just go around on second character.
It seems like second character is used because there was second slot .
But I think your view is good for some people who really achieved it 100%
Hmm…
Would it be better if they allow it on same server
Well hopefully answering your question of why people make multiple accounts. Definitely some people fall into this category if that helps explain why some do it.
Plenty of other people enjoy the leveling process or want to check out other servers. We don’t have a restricted class based system here so it’s not like other games where it’s almost integrated into the game itself.
Even if you aren’t completely done with your main, there are reasons. I have friends on multiple servers, so having characters in companies on two servers makes sense to me, depending on if there is a fun company event or something going on on either server.
Also, for “end game” PvP, it is pretty easy to have a character with great two perker armor, but the jump from there to 3 perkers can take a really long time. So it’s not crazy to have one main that you are trying to 3 perk out and one alt that you are content with 2 perkers, just to be more casual with. Two different characters, two different goals.
It’s easy to swap builds, maybe have 1 toon as a healer and the other as dps or something. Some people do it because they enjoy playing in wars so having alts they are able to get into them more often on other servers.
There are actually a million reasons why they don’t, and a lot of it has to do with cheating, collusion, and a host of other nefarious issues.
Now… Why we can’t have two characters in the same World Set, is beyond me… I’m sure there’s some technical reasoning. But for now, that point is moot since there’s only 1 server in each world set at the moment due to population decline.
You can have both caracters in the same company and use the coffer to transfer gold.
The reason I made an “alt” or used my other character slot was just to level again. It was fun going to level 30 or 40 but I ended up finishing to 60 and only got my expertise so far to like 540 avg. I don’t play it much as it was mostly to just level again for fun.
I know others have friends on multiple servers so I assume people use their other character to slot to play with friends on one server and another.
Then there are the hard core mega companies who have been killing the game where they have “alts” on one server taking over and their “Mains” on another doing the same thing.
I know in games like WoW having alts is very popular but you also can only play 1 class whereas here you basically play everything. But since there is no mail system here either, having an alt does seem useless, unless for like the reasons I gave (and others I am sure). I know in other mmos people use their Alts to mail stuff to either mule, build up specific professions to make gold and then mail it to your main etc.
But they do, they have to. Players with characters on merged servers now have two charaters on one server.
Who cares?
The game has no sub. What benefit does requiring two accounts do? It makes tracking and proving that nefarious activity harder. Embrace alts and you get much better data on the dev side for understanding those fringe exploits.
The people not exploiting arent harming anyone.
Also people multibox two accounts because they had to buy two to have alts. Having them both on adds to ques. Same account wouldnt cause that problem.
One could argue, that’s a bug not a feature. =)
No system is perfect. We all know that. I’m not actually in one camp or the other when it comes to alts… I just want a Fresh Start server. 
But that would mean I need another slot… so there’s that.
If my WoW history shows a pattern, it’s if given a choice, I’d have 10 characters on each server… and probably be rolling 3 or 4 servers/server types.
If only we had a mailbox…
I know many people with both two charaters on the same server from mergers and multiple accounts and a few with both.
Multiple accounts on one server lets you safely trade. They really need game mail bad in this game.
I did it for extra storage and better coverage for crafting buffs. I originally also used both for multiple cooldowns for refining cooldowns.
The biggest draw has been extra storage. A lot of work to get extra major houses but the extra storage is nice.
Its not really possible to multibox here without auto follow.
It does let you keep an eye on the TP while your out doing other things if that is your thing.
Historically ive played multiple charaters for class changes not really a thing here.
More recently the 25 mutation limit is another thing you can work around with a second account.
You mean AGS being able to merge servers? I AGREE as someone whose been forced through three merges. Its totally a bug…
I dont see any other way they can handle it. Every other idea to handle it creats a PR nightmare.
I see it as a legitimate reason to…
Preachin’ to the choir, I would’ve been just fine staying on Rosetau.
Have a kind of different immersion and easier to classify our stuff ! and less stuff in our banks.
I do think they didn t listen and now it s too late !
I would have loved to have 2-3 differents characters with the same bank spaces and in the same FACTION also … and this would have no repercusion on Dupe or Cheats or Treason Faction things.
Now with the merges since the 1st merge, some people have 2 characters on the same account with 2 differents Faction… this is totaly silly and made a lot of players leaving the game
It’s down to preference really.
For me every character has a story. They all arrived onto Aternum with different goals, asperations, sought out different ideals, and having a variety of different experiences along the way.
I enjoyed 1 - 60 because there was progression to be felt. Until they added expertise, now being 60 since then has felt like a chore. Literally a system designed to choke progression in an effort to stop the loony toons that consume all the content then cry that there isn’t any.
I have 3. The healer I started the game as, a tank and the third one is still up in the myths what to make. Maybe an assassin. Normally people have multiple characters for a variety of things. New World is however an extremely restrictive game. On my favorite mmo I have around 40+ characters for various things, some for pvp, some for pve, some for gold grinding, some for market brokers, 3 for fighting in the leaderboards, 1 to establish the guild n put all my characters in it, some for crafting, some for resources, lsit goes on.
2 per region is bullshit.
Non issue since it can be done legitimately with multiple accounts. Just have to be ultra secretive like eve online and vet people for info access. Need to know and 98 % dont need to know.
