That is awesome I would love to have that as a option to xmog.
they could do a range of rune transmogs what create those glowing runes along weapons as an enchanment slot transmog. i think that might be an easier job. back in the day when Dks were coming I was reading the discription and it said they weild massive armors and rune weapons and i believed DKs were getting a unique weapon type rune weapons and Massive armor which was stronger than heavy armor coz they couldnt wear shields and that would make up for it lol i was young and nieve back then, but i dreamed of big chunky unholy armor
