Unfortunately, we cannot provide you a roadmap yet. There’s a lot of things in the background, but giving you a roadmap which we possibly might not be able to complete during the year would not give result you’d like to see. If we get anything new, we’ll inform the community.
Sorry for the late response. Xbox One should be working now. Also there’s no specific timeframe set for the event Arkfalls. They spawn randomly, so there could be moments when you approach three Major event Arkfalls in a row and then only Hellbug spawns for the next two hours.
It depends which version and server. There might be more players on NA servers than on EU servers. If you play in the evenings and on weekends then you might encounter more players than in the mornings.
