Risking serve=a lot of errors. You realize this, right? More errors or aces mean that game is ongoing without any rallies. What is the point of giving so much emphasis on only one single element of the game? There's no logic to defend it compared to let say a monster blocks or attacking in 3 meter line etc. you can see how male volleyball has already enormous amount of serving error, which makes the game slower and more boring
They already making a lot of erros by risky serves, cuz there is no alternative to slow down top opponents, especially at this level. No team spares already risky serves today. That rule wouldn`t change anything but at least rewarding it.
