Vixie my Season 3 looks sooo awesome in Glyph of Shadow - also if you haven't seen it yet it's still quite dark, we still have shadow sparkles trailing us - the dps dk in my guild still complained that it did nothing and he couldn't see the colour in my armor because I was in shadowform (except it was glyphed). I don't think its a betrayal of the shadows to use it - especcially now that we have xmogging to make us look super cool and iconic of our class
