Most of war hero's bonuses come into play minimally. +50% honor only matters if you're hoarding hp. -50% train time and draft costs are irrelevant in war since you should had already trained before exchanging. Not positive what you're plan is with that... Immunity to dragons is ok I guess but it certainly doesn't outweigh -50% losses. And then immunity to plague. Natures blessing. So there's that.

I picked a pers to use for the entire age and all I got was this stupid dragon immunity.
