Yeah although it's quieter now I don't like the "new" grunt either. First of all because it reminds me of Vika's grunt and second because it's a bit delayed and it just doesn't feel like a natural thing like her previous one. Sometimes it seems like she forgets to use it and she remembers it after she's hit the shot
But I don't understand how it just changed like that all of a sudden. I mean I can't imagine Maria was like "yeah I should change my grunt cause I want to sound like Victoria"
