[2019] New Light Has Not Been Implemented Well

IMO Bungie should have done a much better job implementing New Light. I've got 4 of my friends to download and play the game and so far whilst they all love how tight and smooth the gameplay is they are all utterly confused and have no clue what to do. They don't know what the main mission is, what the DLC is, where to find new missions etc. Bungie have simply let all these New Light players loose in a huge world with 2 years of content and expect them all to know the order to play the game. They've even removed the missions from the milestones tab, I told one of my friends to open his milestones by pressing E on the director and that should tell him what to do next. Nope, all it said was Eris needs help on the moon, prompting him to buy Shadowkeep when he hasn't played any other part of the game.

This isn't just my 4 friends too, this is a hot topic on the Steam community hub and in general there's mass confusion among all the new players. They need some guidance, they shouldn't need to figure everything out like Dark Souls. A bit more effort from Bungie in guiding the Kinder Guardians directly in the game would be appreciated, I feel like New Light was implemented very lazily as if they didn't really expect any new players to start playing. A simple thing such as milestones for all campaign missions, starting with Red War, could help these new players a lot in figuring out what to do.

TLDR; New players have no clue what to do as Bungie has made an outstanding move and tucked away all old campaigns in a dark corner of the tower, Amanda Holliday. They are not guided to her or even told she is the source of old campaigns.

EDIT: I'm fully aware Bungie have made New Light players skip Red War, CoO and Warmind so they can jump right into the new DLC or Forsaken. However this is exactly what's causing the confusion. Most of them are simply not aware of that because they've never played the game before, and most of them certainly aren't going to immediately drop £30 on a new expansion for a F2P game they're trying out.

Also putting the previous stories on Amanda Holliday of all NPCs was a stupid idea. Most New Light players complaining of confusion had trouble finding her and weren't aware that she was the source of previous stories. They aren't guided to her or even told she is the source of old campaigns!

EDIT 2: People still commenting that new light is fine and new players just need to "be less stupid", please take a stroll through the comments or the steam community hub, thanks
