Putting the request in on their forum should give others the opportunity to reflect your feelings. I'm sure if everyone or even a lot of people.. were to resonate that it IS important they would adjust things accordingly. I think it would be great, but i have yet to even mess with C2's audio effects at all..
audio is pretty unimportant for mobile.. most people play games with sound off or very turned down.. music often adds a lot of bulk to a game. it's shame because i like writing music, but when faced with efficiency and the reality of mobile experiences.. it becomes hard to invest much time / energy / money into sound.
