This is not a prideful oh look at me post. This is a serious plea to just crank up some serious fright into the heart of us lone wanderers who expected more of a challenge from survival mode.
What I would love to see is Bethesda implement some faster more powerful enemies that have a variety of different attacks. How great it would be to get my neck snapped by a stealthy ninja like gunner who comes up from behind. Maybe if your perception is high then you can hear him but if not, you're dead, that sorta thing. Snipers and increasing the Fatman usage on us. Behemoth's should super jump and landing on you should be instant death. Deathclaws should stalk and be 2 times as fast. Stingwings should be 3 times as fast and their posion should feel like getting stung by a Cazador! Raiders should ambush and pop out in junkie gillie suits and shoot the heck out of ya! Ghouls should immediately turn to running once spotting you and not ever be there sluggish selves from afar. Finally, Super Mutants. They should be able to rip your head right off your body if after 3 seconds you stay to close.
Anymore suggestions would be very welcome!
