@hipsu555 I understand what you're saying about getting a separate progression system and having players choose between a PVE only game mode, or a PVP-PVE game mode.
Here's one reason why this won't be added into the game.
Imagine you have a choice, you are going to start a FOTD and you want to stack it 6 times, would you rather join a PVP-PVE server, where you can get tucked on, killed, have your loot stolen, be worried that someone is going to ruin your experience at the FOTD. OR, are you going to take the PVE only route, where you don't have to worry about other pirates or getting your loot stolen?
99/100 people will choose the PVE only server because there is no risk. The problem with this, is that the PVP community will go into games, and there will be next to nothing for them to steal, because everyone would go into the PVE only mode to do their missions.
A lot of these arguments are based around the PVE community, yes having a separate game mode for ONLY PVE would drastically improve the PVE community, because they wouldn't have to be worried about losing their loot. However, no one considers the PVP community, and how that would affect them.
If Sea of Thieves added a PVE only mode, most players would never even attempt to play the PVP-PVE mode, because there would be no incentive to do so. It is a much safer and better option to play the PVE only game mode so that you will never get your loot stolen. If you want to get something like this into the game, you would have to find a way for it to benefit the PVE and PVP community, because most of these arguments that people find are only helping the PVE'rs not the PVP'rs
Another reasons why this will never be added into the game is because the developers have said that they will never add a game mode with strictly PVE.
