F4 Deathclaws are terrible. They do not act like powerful, top-of-the-food-chain creatures of the wasteland. Instead of trying to be as quiet as possible by running bipedal with their infamous claws outstretch (readying to slam down and rend flesh and bone apart), with the only infamous sound of their claws clacking upon the ground and heavy breathing of a beast in motion and by the time you hear it, it's too late, they instead act like fucking idiots, roaring to everything in a 5-mile radius that "HEY FOOD, HERE I AM!" making a fucking huge commotion to make any prey run the exact opposite of it. The only time this should be done is mating season and Deathclaws are challenging one another who has the right to be Alpha, or their initial ambush of prey turns out to be a human being, a terrifying creature that can easily kill them, which would have the Deathclaw try to be intimidating as much as possible to scare the human, or at least make them hesitant. However, these things just...do it any fucking time the wind blows their way. Stupid. Their claw design is fucking awful in terms of killing power, and they don't act like predators, leaping towards their prey and using BOTH claws to maximum effectiveness. I definitely preferred NV's Deathclaw method where breeding is a bit slow, what with only 5 babies and such. Fallout 4 makes it look like Deathclaws are breeding like fucking rabbits. Kinky, but stupid.
as for the body form of the Deathclaw, it looks awful. They exaggerated the hump on it's back greatly and made giant fucking spike decorate it. Idiotic. They should totally make Deathclaws do a stare-off on humans when humans encounter them and such, as a way to show them not extremely aggressive during resting moments, more like "this is my territory, back off, hunter".
