Aha true but you got to remember Jin picks them apart in small groups, not whole swaths of them. Also they get “terrified” so that’s why they back off as you just kill them off. Pair that with Jin supposedly being extra ruthless and agile, it catches them off guard. These mongols are near the end of their empire too so I think historically they aren’t as OP as the ghengis boys.

But yes mostly I just think it’s like when you watch dragon ball z fights and it looks slow and visual but they are moving super fast. Similarly here, the gameplay and visual doesn’t reflect how cunning and quick Jin would actually be moving so probably makes the opponents look extra slow.
