Yes, I’m aware of that justification. I like the idea in principle, but it doesn’t hold water in this game, because the mechanics they used to simulate ultra-realism are not realistic at all. Picking up a weapon in real life doesn’t impose a state of bodily malfunction where you have about as much control of yourself as a blind drunk standing on one stilt. I’ve used swords and bows. Even my very first time, there was never a point where I suddenly found my arms or legs failing to work at all. The implementation here is a ham-fisted attempt at best.

Clearly, though, there’s an audience for it

It seems so. If some people enjoy slogging through those mechanics, then I’m happy for them. I have better things to do with my time.
