Until you tried them?
For me it is rogue.
Never felt liked the fantasy of being backstabbing, thieving and sly son of a gun.
Played this game since tbc and never played one then all of a sudden I play one and I have never enjoyed a class so much.
My idea of their fantasy has changed as well.
I see them as agile warriors, special tacticians, lone wolves.
Any one every been quite pleasently surprised by a class they always put off playing?
