I don't even know what I am....I'm all three I think =/
Every time I level up, most of the time, I get a new 'fate card' and no matter what it is I chose it, then I switch back and forth if I level & no new ones have been unlocked. I try to spend at least 1 point on each of the three tabs (Finesse, Warrior, Magic or whatever).
I've got like 3 points on longswords, 2 on greatswords, 1 on hammer. 5 on lightning attack ect. I don't spend much on Finesse just upgrading my bow skills.
I'm at level 15 now I think.
