Because it’s a niche market, like I said.
That’s what Amazon realized and integrated their PvP game into a PvE game.
Which is what SO many other MMOs attempt to address.
“Why doesn’t more studios capatilise on PvP?”
Because they do.
Like … literally all of them.
Pwned.
You should start selling your expertise, you clearly know more than everyone in the world on game development 
Logic fail; rhetoric fail; discussion-board fail.
Pwned again.
(Now I see why you hate PvP so much)
Strange really that a stale PvE catered MMO grew to be the biggest MMO on the market with 12 million subscribers at its peak. Hm, strange.
Another day, another troll who lives in the past and uses it to justify stupid decisions in the present.
Fail.
Pwned.
Wrekt.
Should follow your own advice on the first part there.
Troll says, “I know you are, but what I am I?”
Sorry to pwn you so hard with logic and reason.
I argue my view from my perspective, which is basically what everyone does on the forums. I think an easier way of say it is “having an opinion”.
That’s a lie. You spewed a bunch of uninformed and sanctimonious bullshit about “investments” and “returns” and “basic economics”, in addition to lying about being honest.
Then you got pwned by a simple reality: Demand for PvP servers … which is literal “basic economics”.
Everything you’ve said since is merely triggered dishonesty because you wish that you knew what you were talking about.
Which is why when you say stuff like this …
I don’t think PvP servers will work based on that aspect not working in other games before as it always led to problems such as major faction imbalance that were never resolved. And subsequently they moved away from that aspect entirely because it divided resources too much and they were better spent at the game as a whole rather than locking them to one aspect primarily.
… no one should take you seriously.
And if they opened a PvP-only server, then all you could do is cry and be wrong.
Sorry to pwn you, but thanks for playing.
