Personally I'd much rather have items that have something unique or cool about them that has nothing to do with how they look. Glamour as a reward sucks because it's so hit or miss and there's already a ton of glamour/mount/whatever options in the game.
Gimme a sword that shoots fireballs on a proc or something. Gimme boots that let me use stealth on combat classes (other than ninja). Give me an axe that makes Mercy Stroke hit super hard but increases the cooldown. Who cares if it's a little bit imbalanced? Item level is going to outdate it anyway, and if you can kill the raid you're already curbstomping everything else in the game.
