I think if you hit someone with Melee, it does the same " Ahhhh!" like it does normally. The problem I see now, is that if someone blocks your hit, it stills makes the same noise as a normal hit, and I never know if they blocked it, or they're gone, and Im free to back off for a second. Therefore, Im suggesting that when you block an attack, it plays some sort of sound effect, and when you hit them succesfully with melee, it plays the normal sound.
