The proposed skills/auras seem to me like the formations in a way, just put in a more pleasing way. But in any way if you add these auras to heros and people put them in the first line you must have a heavy loss when u lose them because there on the front line like moral -75%. Otherwise everyone will do it to try and get th upper hand from the start, giving the moral decrease would mean that you should only really use him near troops to make these auras effective when all is almost lost and you need a miricle.
But as ive said they look more like what the formations are proposed to do.
