I want to see this so bad. Ive read on how the Orcs always had a history with the demons and hes the lord of sin while Thrall is like... Amazing? I would love to see this play out. I don't expect to win since I didn't put in a background or a real battle scene so I might be already disqualified but, heres my entry
Thrall is the Warcheif of the Orcs with shamanic powers and a Hammer to channel it also. Hes like an Orc Thor! But to me more badass.
Azmodan is the lord of sin and is very powerful commanding legions of armies and minions.
