We haven’t finished killing off all the Black Dragons yet - we still have to clean out Baron Sablemane’s forces… Also since the Helm of Domination is gone, why hasn’t the Scourge run rampant across the world yet?
How about we add another class which use ranged weapons: Inquisitors! The three specs could be: Ordo Hereticus (anti-humanoid), Ordo Xenos (anti-anything-not-humanoid), Ordo Malleus (anti-demon). Hell, make their Ordo Xenos the tank spec, and give them cloth armor, making them the first cloth tank!
For the Emperor!
