maybe instead of "hero" they should be called "generals"
cuz that's what they are i suppose the strong guy leading the hordes
tbh it would be nice if a hero/ general would be more of a army buffer then a actual combat unit
atm i use my hero to solo quests with... he tanks like a beast ... has a super heal ... does aoe damage... its kinda lame...
wouldnt it make more sense if the hero or general is the guy who gives moral and boosts your troops there performance while sitting in the back sucking his thumb on a fat horse
it would give you more strategical options aswell you could fight the army buffed by its general
or try to get that nifty general hit by a trebuchet :P
