The sound that replaced Steve's pain sound is annoying because it makes no sense. That annoying "tchk" sound that is just like a glitch or bug sound. Why they got rid of the "ooh" I'll never know.
For girls who play minecraft, of course! It sounds very male, what would guys think if 'Steve' was 'Silvia' , and sounded like a little girl? It's the same way. So they changed the sound.
Btw my least favorite sound is wolves & ocelots hurt sounds, ESPECCIALLY when poisoned. It's SOOOO grating!!
