Blessing Effects and National/Theme Starting Spells

Alright; just another question here in terms of "why this?"

Why do all T'ien Ch'i have Flight? There is no national mage that can cast it unless you get a lucky pick or useless(S&A have flying Celestial Masters).

The only hero that can use it is the Master of the Iron Crutch. Perhaps if Flight was a Commander only Ritual spell that give permaflight or some spell to replace it.

Maybe I just don't see the usefulness of that particular spell being a "initial spell". Even thematic.
