That's a ridiculous way to look at it. "I can't have infinite ammo? How unfair". People don't play games to walk through Cut scenes and one tap all their enemies. If you want something that easy there's minecraft creative. Better yet, games like Halo with difficulty settings where you can change it and it not affect anyone else. This game is meant to be progressively challenging. There's no difficulty settings beyond make it extra hard for improved rewards - if everyone could take a stroll and have all of the same gear, what would be the point? There's no point to "achieve" anything.
