I think others have covered the why of it adequately, so I won't reiterate.
What I will add is that being less than epic can also be very compelling from an RP standpoint. My own main is a talented, yet green, Conjurer who had never even heard of something called a White Mage before he met another roleplayer who claimed to be one. He's poor, uneducated, has never seen a primal or fought Garleans face to face, doesn't possess the echo, and has only heard of the Scions in passing. Yet he's still fun to roleplay and is often sought out by others /for/ roleplay.
Edit: Some of that will change, of course, I'm just listing it to drive home the point that he's really nobody special.
Point is, you don't have to be on top of the world to find that world and your character compelling.
