Heyo, I put together a few videos showing EVERY location of each lost sector area across all 4 planets. Some are very well hidden so If you can't find them you can always reference one of the videos. Doing these nets you your characters missing subclasses and can level you really quick. I level 20 well before the ending of the game.

Edit: Will just point out that these places are farmable for gear and tokens. Edit 2: If you find that you don't need to use these then don't, that is perfectly fine. They are more a reference to those who don't have to time or patience to hunt down entrances to these areas. Please have respect for BOTH sides of the playerbase, not everyone plays the way the other person does.
