The map is very big. I guess it depends on exactly how much of the map have they explored.

But if you are new, and they are on day 130, if they have defeated several bosses it will make it rough on you to progress. This is because of raids triggering randomly that bring lots of enemies at you.

Just starting out, I'd personally recommend doing your own map. Once you get the game down good, then join others who are like minded.
