Meanwhile druids are still waiting for old cheetah and the teased new grey one.And how about giving us every possible color for lunarwing and warden owl. Im still mad that worgen got the purple and white colors that where meant for nightelves....
We definitely need more cosmetic glyphs. It's been a real bummer not having any this expansion so far.I know most of this if not all have already been mentioned, but I would love to see more Druid forms/color variations, more Warlock demon customization, spell color customizations, more ghostwolf forms and more elemental customizations/colors for Shamans and Mages. I would also love mount customizations for all mounts, like hair colors, flowers, jewelry, feathers or braids added to horses, and other options for all the different mounts, etc. For pets, top hats, chef hats, party hats, maybe a tux or a dress for some. I know it would be a ton of work, but would be cool in the future!
A good start would be re-adding the Ascendance glyph for people that don't like turning into a flaming clown with serious spinal injuries.
