I really play the character as a warrior. Even though some stats indicate that the character is weak in some areas, I can't tell the difference between this survivor character and the warrior character I played first. I just wanted to try the survivor but found no particular advantage. I do prefer the warriors special move since you can do damage while invisible (right click only with special move skill active, left clicking makes you visible). The other two classes special move don't really seem to help me as I usually play melee anyway. . . =)
I no longer load up all magic skills with points since I usually use only Lightening for my ranged weapon along with a few other skills for other things. I place my skill points more carefully now whereas my first game I was trying to raise almost all skills . . . resulted in a weaker character build IMHO. Most of the other skills were from found books and rewards from quest completions.
