Aren't Blind Deathclaws more perceptive than regular ones?
Yeah and I found them much tougher then there... less blind counter parts.
As for the topic at hand...
I vote NO.
I remember FO:3 there was a town south of Old Olny (the place that had queen bee, and robot man fighting each other) that I loved to use as a selling point.
I remember going to said town, and wondering where everyone was...
It was horrible... body parts, and blood was everywhere.
I had no clue what happened till I turned the corner, and found a half dead Deathclaw charging me.
1 Deathclaw killed my favorite selling spot, and some NPCs I had grown to love, and I was powerless to do anything about it.
Was it more realistic? Yeah
Did I enjoy it? Nope
