Jump has always been silly in D&D.
'High Jump. When you make a high jump, you leap into the air a number of feet equal to 3 + your Strength modifier if you move at least 10 feet on foot immediately before the jump. When you make a standing high jump, you can jump only half that distance. Either way, each foot you clear on the jump costs a foot of movement.'.
So if I have an 18 STR (Highest STR I've ever had in D&D) that's 3+4 = 7 feet. My 18 Str Barbarian can just two whole feet higher than I am tall, IRL. He can physically hurdle me while I am standing up.
Also, the world record high jump is 8 feet. And I'd say an 18 STR is 'world record althletics' level.
'Long Jump. When you make a long jump, you cover a number of feet up to your Strength score if you move at least 10 feet on foot immediately before the jump. When you make a standing long jump, you can leap only half that distance. Either way, each foot you clear on the jump costs a foot of movement.'
Again, using my 18 STR Barbarian, he can make a running jump of 18 feet. Keep in mind, the world record IRL is 29 feet. And I'd again say a dude with 18 STR is at the 'world record athlete' level.
So, if anything, D&D is actually toned down from real life, or matches it closely.
That said, the animation will hopefully be tweaked so it looks more natural.
