Water reflection alpha is too high, particularly in underground/dark areas

I really like the new texture maps for water surface reflection, but the alpha is too high in dark/underground areas.

If possible, I'd suggest dynamically modifying the alpha value for water surfaces so it doesn't reflect when it's dark, and increase the alpha when there's bright (i.e. outdoors or strong point source like skill/effect) light around.

If it's not possible, I'd still like to see the alpha value for the reflection texture turned down a notch or two in general.

Keep up the great work with the incremental improvements to the sound, art, effects and environments! ;-)
