I suppose Lydian Dominant could also be called Mixolydian Augmented 4th...

Oh, and don't care about how it is used in metal or jazz, or if it is common or whatever. Just learn the scale and use it. Of course, guys will complain that they can't use it because the song jsut does not have room for it. It's like someone trying to fit a F# Pentatonic Major into a C Natural Major, unless you are trying to be interesting.
