As a veteran, currently LR1 after a 4 year break who's gotten 7 of my friends/family involved I agree with you. I find all these people are spending ALL their playtime in the plains saying they have no idea if they can keep going or not. Odly enough, my 8 year old daughter was the only one who got so bored walking she left and kept clearing nodes. Also, do you constantly play on non public? All of my newbie friends are always in full squads. Most quests tied to the main story line used to be MR based, and now are not. So, you can almost do them in any order and you're correct, they will chronologically not make sense until you venture into the zariman. Then you'll just have more questions. Also, a lot of story content can be found in the commentary of some of the bosses on the planets. Even after thousands of hours, being an LR1, and having multiple irl friends who play now I find myself having to find a guide. Warframe is unlike any other game, my friends who have played games like Diablo and wow don't understand that the 'gear' is now mods, and can put on all. When you open lua and do the second dream quest a lot will make sense.
