suggestion: class titles

So I had a pretty neat idea and wanted to throw this out there. It would be pretty cool if there were class quests we could get in order to earn titles specific to our class. For example, Gladiator for a warrior, or Grand Magus for a mage. It would be a fairly difficult quest to obtain, similar to the green fire warlock quest in difficulty, but it would be pretty cool for RP'ers especially. I'll give a list of ideas I've come up with so far for each class:
Warrior- either Warlord or Gladiator (possibly made faction specific)
Paladin- Champion of the Light
Hunter- Ranger
Rogue- Pathstalker
Priest- High Priest
Death Knight- Champion of Death
Shaman- Elder Shaman
Mage- Grand Magus
Warlock- Necromancer
Monk- Brewmaster (I know its already in the game, maybe we need to find another?)
Druid- Archdruid
Demon Hunter- Ascendant

Blizzard really wants us to feel like heroes these days, and make us feel as important to the game as some of the greatest npcs so why not give us a chance to earn titles that show that?
