Ascension RE system is so great, it has kept me so engaged and happy for the time I've been playing, I would love to see a cosmetic RE section that can be applied to tabards and shirts. Things that change the color of spells, the look of things (this could be a place to put boomkin/shadowform/treant stuff). The jazz RE comes to mind, just fun things that don't take up a slot for actual power RE's but increase customization and fun :D. I could see these being DP/RE's depending on the level of change just like it is now.
@Rubis this already exists. it is a currently Vanity items.
I fear the day when players won't have to sacrifice a RE slot for the jazz RE. That tune is going to be permamently burned into my mind
@Vulpinenin haha, that's fair. XD
