Progressing thru the game doesn't mean having harder quests = better rewards. Its a natural progression that in a lots of cases can be minmaxed to the point entire game is trivial = CP2077, Horizon, Witcher.
Thing is, later quests aren't harder, and even if, only slightly.
Dishonored with more amulets and more skills = ZERO difficulty, this game became so damn trivial.
Horizon difficulty was pretty linear.
If you want to compare it to wow its like first raid bosses vs last bosses. Difficulty setting in menu = lfr, mythic, heroic. With a difference that in games playing on easy doesn't give you worse gear than on hard.
AAAAAAAAAAND lets not compare initial quests aka tutorials and introductions, to mid game vs end game.
