I'm not sure who decided to write this garbage, but jousting tournaments were not a blood bath where the contestants murdered each other to the cheers of the crowd and knights openly cheated with no one batting an eye.

In such tournaments, knights often used blunted weapons and there were clear rules to prevent the contestants from getting killed. It was never a fight to the death. Death happend rarily, thanks to the durability of a knights armor.

Lords send their sons to gain glory, if this many contestants died, they would run out of sons pretty quickly and would gain many reasons to go to war with the people who killed their sons.

Game of Thrones treated its viewers like intelligent human beings. Knights getting killed was something out of the ordinary, attacking your opponent to unhorse them was not acceptable.

House of the Dragon treats us like morons. Thats probably also why they want us to accept that Westeros now looks like New York.
