I am not opposed to renaming Shadowmeld to “Elune’s Magic Burka”. Shadowmeld makes less sense. The way it works in game, Night Elves can use it on an empty field in high noon - with no shadows nearby to meld with.
But if Elune canonically frowned on the Night Elves skimpy attire and gave them magic burkas to hide their shame…(and themselves) that would make more sense.
