This game needs less solo content.

[Doozer]

Solo content kills group content. When you have each person in your free company doing island sanctuary alone, instead of grouping up together for something, then you have less people doing group content. How can you not see that. We need more incentives to group up.

Do you really think Island Sanctuary is why your friends don't want to raid with you or something? If it wasn't in the game they might just go play something like Stardew Valley or Animal Crossing. Removing it or not adding it altogether doesn't make people want to do the other stuff.

People should not be "incentivized" to play specific parts of the game. If they want to, they will. Stop trying to force people into specific content you want to play. Clearly they enjoy the solo content more.
