Now that the expansion is out - which skills will be nerfed first?

The backend changes are the new renderer that is now out.

We are not planning any sort of always online components. The game is primarily singleplayer.

A closed multiplayer setup would require fundamental changes to the game engine, not to mention server costs, customer service, upkeep, etc.

It’s a monumental task, and one that would have had to happen early on, not when the game is years old.
