To add on to what TuxyDoh said, any content you had on battle.net is either free or no longer in the game. Any non-exotic weapons will be sunset and unusable. All armor will be severely outdated and fairly unusable. You're not losing out on much by starting over outside of some exotic weapons and any ornaments/emblems/other cosmetics that you can no longer obtain.

Forsaken is not currently free, but, yes, much of it has been Sunset. Other than that, I completely agree and back up the rest of your information.

Thank you for clarifying. I had forgotten Forsaken arrived on battle.net along with Steam.
