I am just curious as to what classes you all think could use a 4th spec. Just FYI I don't think all the classes need a new spec just some. (Warrior for example) I have a couple ideas of my own.
Shaman - I think most people have thrown around the idea of a shaman tanking class. Perhaps something that uses agi mail gear? Maybe it's related to Enhancement some how?
Monk- Even though it's a new class I was surprised to see that it didn't get a Ranged dps spec. I think they could really make it work with jade lightning, fire bloom, fire breath etc.
Mage - I always wanted to see a mage tanking class that uses int gear. Maybe it's a bit of a stretch but still I think it's a creative idea.
