Well I suppose my judgement would be flawed seeing as I didn't train him very much since he was the game's jeigan. I opted to train my other units more often which resulted in my view on his stats and etc. Maybe I'll pick up Sacred Stones again.... well, after Awakening of course. Also now that I actually look it up, he's very very very broken for a jeigan.
And how just hard is Lunatic anyhow? It sounds near impossible to do on Classic.
