Completely understand why this would be desired right now with the server issues we’ve experienced during launch. Offline character data is stored locally on the players PC, meaning it has potential to be manipulated, so while we could make it so online character progress could go to offline with some effort we wouldn’t allow offline progress to go to the online servers because it would prevent us from doing leaderboards, trade, and in the future other competitive things like races, server firsts, etc. I very much suspect people wouldn’t like to make progress offline temporarily but have it locked to offline - splitting their characters state.
We’ll be making improvements to online stability at mass scale. We have enough real world data now to see where bottlenecks are and how things break in a real world scenario that our scale testing wasn’t showing us before launch.
