I just started playing the Division about two weeks ago, I played the first one many years ago but not much. I have finished the main campaign and now my map looks back red again. I assume I’ve transitioned into the “end game” part of the division. What do I do now? I’d just like some tips on tinkering, mods and builds or just the right direction I should go so I’m not wasting my time. I remember I had access to an Excel spreadsheet for the first game, is something like that available for this game?
