7. Avoid Relying On Fast Travel
Though The Division 2 has a fantastic fast travel system which allows players to visit previous locations with the press of a button (following some surprisingly reasonable loading times, of course), you're advised to avoid this temptation wherever possible.
You see, the game's world is absolutely littered with things to do, from Control Points to "random" events, not to mention all the loot and collectables littered around pretty much every square inch of D.C.
This will not only help ensure a steady stream of XP coming in, but also give you a wealth of materials for crafting.
Relying on fast travel will allow you to quickly blast through the game's critical path, but you'll not only miss out on a ton of the content populating the world, but also much of the game's rich, stop-and-smell-the-roses atmosphere.
