Would CCP be better off if they created a PvE-only server for EVE? Some carebears would argue yes, because since EVE only has a PvP server, they don’t play. On the surface that makes sense; PvP-only games are indeed locking anyone who sees PvP and runs in the opposite direction out. But lets play this out a little further shall we?
On that PvE-only EVE server, the economy would be a total joke. Ships would rarely be lost, everyone could fly around perfectly safe in all-officer fit ships, the most lucrative PvE (null, WH) could be farmed without risk, mining afk would never end negatively, and all those multi-billion-ISK-in-a-transport traders would never be ganked. So unless you also expect CCP to basically completely change the game on almost all levels, the economy part of EVE wouldn’t work on a PvE server.
Furthermore, the PvE challenge on such a server would also be a joke. Remember, everyone is flying around in all-officer fits, which makes them far more powerful than the standard PvE ship found in the game today. Beyond just that, outside of high-sec you can now use a Titan to farm all day without a single fear of a hot drop. Are the carebears expecting CCP to fix this as well? How, tune PvE to officer-fit Titans in terms of difficulty? Just accept that all PvE would quickly become faceroll in difficulty (more so than it already is in EVE)?
And now the biggest question, why the hell are you going to play EVE for years here? You are sitting in an officer-fit Titan, with a wallet full of ISK, a hanger with every ship and fitting you ever wanted, and having safely explored everything there is to see, with all content being trivial and with nothing else to do. What’s your motivation to keep playing/paying?
There is a reason EVE is the only MMO out to grow and maintain sub numbers for more than ten years, and that reason is directly tied to PvP. So while yes, certain carebears stay away, the game has proven that other carebears stay, year after (10) year, because of what PvP brings to the game (among other things, a sink that keeps the economy and basically the whole game going).
A lot of those currently playing WOULD switch to the PvE server, because most people are child-like and would eat candy until they died if you let them. They WOULD get bored and walk away from the game. That is why you don’t open a PvE-only server; because it would allow MMO children to spoil themselves into quitting, and in the long run that’s bad for business.
So help save the kids, and your MMO; don’t go PvE-only and kill yourself and everyone playing!
PS: The same applies to AA. Think about how many of that game’s core mechanics rely on PvP to balance or keep them interesting. How many seemingly PvE-only activities would lose long-term value or purpose in a completely safe world?
