There's a solution if the game is too easy. Use lessor armor or weapons if you like. Some already do this. I know of people that play with only green armor or only use the vestian side arm on missions. Or play things solo which many also do. Or try to go flawless. There is no solution if the game is too hard or made too hard by nerfing weapons. It will be impossible or at least not fun for many and less people will play it.
