None of this changes the fact that once you are 2 hours into the game, you can now roam freely without even worrying about the deathclaws... and then the difficulty and challenge never ramps up. Am I the only one that finally went to finish the storyline and one shot the last guy in the Legion camp with a melee weapon?
Did you play the game on Easy or something? On Very Hard (in addition to Hardcore mode), Deathclaws remained a serious threat even after 80 hours of play. And I believe Lanius took 11 headshots with an Antimaterial rifle before dying. The only easy way to kill Lanius is to dump a ton of explosives on the narrow path leading up to him, shoot him to lure him down and then watch him vaporize instantly.
If you didn't play on the highest difficulty, you really have no reason to be complaining about difficulty.
