Just curious what people think of my proposed horde comp.

I three-box, and plan to only raid on one toon, and I guess farm and explore when I'm not raiding. I only want to dps in raid.

My comp will be-
Mage (raid toon)- undead
Priest- undead
Hunter- orc

I thought maybe of going with a warrior instead of the hunter, but I love hunters! It's the closet thing I have to a main in BFA
