How good is prime Jamie?
Selmy saw him with his first kill at 16, we have Joffrey who can barely chop a book with valerian steel. He also clearly saw Selmy and Dayne the two best swordsman ever in Westeros
What is frustrating, is why he never explained the whole story. He has said multiple times, killing Aeryes ll Targaryen from the back
But he never actually explained properly that all Aeryes was saying was, “Burn them allâ€, and for hours
Obviously it saved his dad, but it doesn’t seem Jamie mentioned that he did that and then killed the pyromancers saving thousands of lives
