[Question] WoTLK User bar idea. possible?

[Scraz]

Okay I had this idea. Well for the death knight there is a user bar of a sword and where there I guess crystal? Or like there mana and I was thinking since there the purple, red, and and what ever color the other one was. I was thinking is it possible to have it so if you're a mana user you would have purple crystals and the less mana you had the crystals would go down and the same theory for the others...

Sounds like a legal addon could do this.
