As a New Light who just started playing a little over 2 months ago, I have to say the progression from New Light to Raid-prepared is exceedingly frustrating. My experience has been after clearing expansion campaigns, and even after getting to max Light, the path from Nightfall Strikes > endgame content isn't entirely clear. I feel that without use of external resources, guides, and hours of YouTube videos it is rather arduous and it's rather frustrating to have the supposedly best content in the game (Raids and Dungeons) be so inaccessable. I don't know if I'm just too new and trying to rush things, but I'm really up against a wall trying to break in to more difficult content.
