What nation(s) are best for fire? (Besides Abysia)

[BigDisAwesome]

I just can't see an air bless worth taking past 6 if at all. It'd be alright for a lot of nations, but it always seems like the points would be better spent somewhere else.

Or you could always just try to scout out enemy armies before they get to you, then decide whether or not to send the flagellants in. maybe do a little scripting magic to try and not get targeted by arrow fire immediatly.
