Yes they are bit loud but I think it's because stage don't have any BGM on. I remember back in the day when I used Neo's Teen Gohan I had to turn off BGM on stage in order to hear his voice and most his sounds. So it's better to be loud You can lowe volume in Mugen.cfg & stuff) that too quiet.
But ofcourse it's up to Neocide. I'm just expressing my opinion.
