I mix. Unfortunately my hero hasn't aquited any "good" swords bit I am disappointed that your hero weapons are the weakest weapon. Maybe they will have augment add on so the hero weapons came more on par with the legendaries
It's not random, just extremely flawed. This thread explains it the best. It's too bad it doesn't take what you do the most into account.
In fable II every hero I've seen looks a bit different in the face. Decisions and actions in game determined shapes of your face. Is it similar in fable 3? I haven't beaten the game but my face only got a little squared(brawny)
Put it this way, all legendary weapons in the game have traits that the hero weapon can morph. So you can end up with a hero weapon that looks exactly as a legendary. Which if you do, that would be funny and I'd laugh and...it would be quite rare
