althought protec have unique skills and all i really think he's not stepping so much in the UNIQUENESS realm for a while.
i was thinking about and thought that maybe they should remake then just as they did with survival hunter.
my idea for a new spec:
General: A fearsome tactician that leads there group to the victory in battlefield, fighting and protecting everyone
Characteristic: have a squire, a "pet" thats a young version of your race, like a kid, that follows and fight by your side. still uses light to heal, shields but gets more buff-like skills and the main mechanic its that the squire copy some of the skills u use every X seconds. (and it would keep avenger's shield bc thats an awesome skill)
Think about a squire following you and the possibilities of quests too unlock new different squires.
