I disagree! This is what you really saw, yet failed to realize...
- 1 lacks years of XP, one is only loyal, for now... etc.
- Its a coming of age style story for Sylvanas / growth into a leader who already has made the greatest sacrifices and still pushed on - a true leader who just needs the right moment to shine (example for us all).
- Voljin expressing his point of view, just shows how much of a good leader he was - the ability to look past someones faults, and his own personal beliefs.
- "the Spirits" is just a completion of the circle, since most of R.L. population on earth believes in something greater/religious.
- Politics - its nice to finally see a female leader.
- Lastly - the other leaders didn't complain (yet?), which shows they know she has the potential.
