That's a good point. Also, anyone who's ever tried to cast a spell irl knows that it isn't always successful. So you might want to add Arcana checks in order to successfully cast a spell. For the sake of realism.Also, anyone who has ever lifted weights for sport or pleasure knows that you don't always automatically hit your max. Some days it just isn't there. And some days you manage to pull off a PB that is noticeably outside your regular range. Same goes for running, climbing and other physical activity: your performance can change significantly based on variables you aren't even aware of. So I think making folks roll athletics or whatever when operating at the top end of what their strength says they can do is perfectly reasonable.
In all seriousness though, I see this as one of the biggest reasons for the general state of the fighter . Anything "real" (ie, anything the fighter can do) is bounded well inside the margins of realism. Generally so far from that boundary that the fighter falls short of what real world athletes are capable of. Whereas, because it's magic, casters are almost never limited in this manner.
Forget about emulating Hercules, your average 20th level archery-specialized fighter can't even emulate Robin Hood (splitting the arrow) without having to rely upon DM fiat.
