having more than two SFX controls would be nice, but for me what I want mostly is the ability to tune out or down the more annoying, persistant and meaningless noise without losing cooler sounds, or ones important to the game. I'm guessing that some people get put-off by some of those sounds, like the howling wind on silan, or the mektoubs in the market while you're doing a lot of trading or crafting.
