I have to say
Warden(shadow strike)
Beast master(bird which sucks *ick and level 1, still to good at lvl 3)
Blade master(windwalk great harrass and in battle to do some major damage, plus ultimate in special spots will invisible to good)
man if their was a fourth it would be death knight, guy is like the sid vicious or gg allin of warcraft.
aint hardcore cuz you spike your hair when a jock still lives inside your head
