It's not like those things really matter in the real GoT anyway. Just look at the series/novels.
Jaime Lannister - hand chopped off after being captured by the Bloody Mummers. Worth noting that he was travelling with the OTHER best fighter of his generation, Brienne.
Robert Baratheon - killed Rhaegar Targareon single handed, killed by a pig.
Eddard Stark - killed by being a political dummy
Oberyn Martell - head squished because he was cocky
The Mountain - speared, poisoned, zombified
The Hound - fell off a cliff
Robb Stark - stabbed at a wedding
Knight of Flowers - burned to a crisp (novels)
The beauty of Game of Thrones, is the realism. The greatest fighter in the world runs into 5 guys in an alley, chances are he is dead, the only difference is how many he takes with him.
