I always resort to popping in and out of a building, getting in a few hits per try, and eventually whittling down the deathclaw. It just seems silly though.
One time, I managed to Fus-Ro-Dah it, or at least, the effect was similar. I had taken off about 1/4 of its health popping in and out of the doorway, when suddenly the deathclaw launched itself into the sky! I said "Oh no, it must have jumped onto the roof or something, now what?" But after a couple of seconds the deathclaw plopped down onto the ground, and died. So somehow it got launched way, way up into the air, and died from the fall. Hooray physics!
So that makes me think, they should set up some kind of see-saw where you knock a car off a ledge, it hits the see-saw, which you bait to get the deathclaw onto it, and it gets launched into the sky and dies upon landing. It'd be stupid, but less stupid than the current setup...
I somehow caught insomnia... from sleeping. I already had the fatigue disease... so now I want to sleep all the time, but I can't. And somehow, antibiotics can cure me of this. REALISM!!!
I also installed a mod that allows me to save in survival mode, because sleepy time simulation mode isn't what I had in mind for survival. Still, I only save in safe places, but now it's up to me not to abuse this. I do wish they had somehow worked dying into the game somehow though. Like dying made you lose caps/exp/something but whatever progress you had made was still made. They could handwave it as the institute not wanting their "Backup" to die and having installed a teleporter in you... or something.
