@Delphic: He has potential to be able to channel lightening with out it but he has far more control with the hammer, also the hammer does give him the ability to fly. Basically he needs the hammer because he hasn't reached his full potential.
The hammer is basically a crutch. Thor was demonstrated to be at his peak potential as Rune King Thor, needing Mjolnir no more.
What do you mean by this?
As Rune King Thor, he become as powerful as Odin, basically to the point where he didn't need Mjolnir anymore to utilize his powers to their fullest potential. Currently Thor can't access his full potential and utilizes his hammer to direct his power. At least, that's the way I see it.
