i never use a captain with any weakness and most of them has rage how i got them is, i fnished the game i dominated all very strong orcs and i has about 200k money and i spend all my money to buy chest and i made a new game, now my whole castle legandry and all of them has 3x bodyguards, none of them has weakness specialy fire/poison (there is few orcswith that has fear of pinging/execution/stealth and they are bodyguards not warcheif) atm my all warchiefs are legandry and bodyguards some legandry some epic, so if u got the time and wanna get best orcs making a new game after farming strong orcs and sending them to the garizon, takes time but without spending zero dolar u can have best army
