To answer how I made such a multi character:
1) I am not good at anything, I am ok at a lot of things, it is his versatility that makes him viable. You know how most characters are "Primary this" and a "Secondary That". Well he is a Secondary that on all of his roles
2) Synergy: He is Race=E, Attributes=D, Resources=C, Magic=B, skills=A. He has poor physical stats, but thanks to magic and a little bio-ware he can hold his own (Spell Increase Strength, Reflex boost, etc...). Mentor Spirit Bear helps a lot too
