@theocitylegend: Oberyn was a fool. He wanted a confession when he knew the Mountain killed his sister and her children and he clearly had the upper hand and could finish him anytime he wanted. He got sloppy and he lost the fight. That's what matters. So I don't know why it shouldn't be counted as a feat for Ser Gregor. By your logic, every fight in Westeros was won due to circumstances or unweighted factors. Circumstances,luck,unweighted factors are all in the framework of battle.
