Raids and Dungeons are the best part of this game and frankly the biggest difference between it and every other like game on the market. The mechanics are by design supposed to be learned by the players themselves and Bungie leans heavily into player puzzle discovery as a pillar for everything. Even after day one completions players are always finding better ways to do things or cleaning up strategies. Problem solving and critical thinking are a big part of the endgame and a core fundamental. The game doesn't point you in a direction because it wants you to figure it out.
