WoW cosmetics systems are outdated!

With WoW growing focus on cosmetics as a reward, the way they work is completely outdated. We now get hundreds of fun cosmetics in the trading post, tier sets, and quests yet using them feels bad or annoying, especially for casual players.

1: Applying cosmetics should not be a gold sink now that they are such a focus and even paid with real money in the shop. It actually removes the value of having as much since you don't feel like changing them every day. It doesn't make much sense if they're selling them.

2: Transmogs should work on slots, not items to provide a smooth and fun leveling and gearing experience. The transmog and saved outfits UI need a massive overhaul as well.

3: Character and even Specs specific favorite mounts/pets should be a thing to add value to your collection.

4: Glyph and Certain toys (like hearthstone, trails, ect) need to be reworked in a cosmetics UI for spells and effects. Could also introduce class skins for class fantasy instead of Hero Talent making a Goblin hunter night elf themed.
