The answer to your question is not simple. It all depends on what you expect your character to be like. It is all up to you and nobody can tell you on what skill to pay special attention. You have to decide on play style and according to this decision make necessary arraignments to suit your character. What ever you decide to do, make sure you put a lot of effort in it, because it is something that will follow you as long as you play the game. Unless you decide to open another account and go over it again. But I dont like this, because you will have to give additional money.
