I'd say the problem is there are few ideas period. Like Destiny isn't exactly bursting with originality, but it clearly has a lot of work put into its worldbuilding, aesthetic design, cool guns, etc.
Like compare the enemy factions. Destiny released with the Vex, the Fallen, the Hive, and the Cabal. All of these had well-defined back stories, visual and audio identities, gameplay, etc.
Anthem released with... The Scar, the Dominion, and a bunch of random monsters. Neither the Scar not the Dominion are really interesting baddies. The Scar are apparently based on insects? Their main visual identity seems to be having a lot of spiky bits, but they're still power-armored humanoids that basically act as bullet sponges. Well what about the Dominion? They're... Power-armored humans. Huh. Really exciting. And then you have some of the biggest challenges in the game being random Titans that just... Exist? It feels so half-baked.
