the dragons wouldn't move without yona
aside from physical prowess and battlefield tactics (Yona does have those, though of course less than Hak etc., or she's smart--at least), she'd be great for the army's morale in case Soo Won becomes unable to fight--she's Kouka's princess + King Hiryuu to the dragons after all :D
She has war knowledge to some degree and considering that she's been in some and at she's been at Hak's side all this time I think she can lead the army with Zeno's help
youre heavily underestimating her which is ironic considering almost everyone in the story underestimated her and they all ended up shutting their mouths when she proved them wrong
I'm not underestimating her. I'm just saying she isn't ready. She doesn't know the units in the army as well as soowon does because she never learned. She won't have time to learn now because the war has already started. I'm sure kyesook and the sky tribe's general will help her tho.
Uh, why yona? Yeah she can have the dragons help out through her commands, but I don't think she can lead an army. Hak isn't with them so I think that's why Kyesook couldn't ask Hak to lead, and had to go to yona instead.
