Keep in mind that Warding breath can only be inherited by melee heroes which have to be either infantry or armored, so your mage choices are out of the question.
Yeah, it is kind of annoying. If you'd be willing to consider some other choices, I'd say you can never go wrong with a DC weapon wielder and especially with lightning breath dragons. Herores like Fae or maybe even Nowi can benefit from warding breath greatly.
