The Glyph system should be reworked into a cosmetic talent tree that allows your to tailor your spec to your aesthetic taste.

For Elemental Shaman you should be able to specialize cosmetically as a "thunder shaman" or "Earth Shaman" across a range of cosmetic talent choices separate from the dps talent system.An example of a row for Fire Mage could be the choice of Blue Fire, Red Fire or Smoking Fire as a cosmetic talent row.
