I am going to bring this up since this apparently has and probably will not be addressed.
So we have the fight with Saurfang Vs Sylvanas. Personally their is more wrong with that entire cinematic, but I want to focus on a particular point.
In Orc culture and Horde tradition it is clearly stated you cannot under any circumstances use a magical weapon in a Makrok.
Saurfang took a weapon which had magical powers coursing through it and used it against Sylvanas.
Sylvanas used two daggers I guess you can call them.
For all purposes, Sylvanas was 100% in the right to use magic then since Saurfang shows he clearly gives no shit about the rules himself.
Not only is he a traitor, he is a hypocrite for using a dishonorable weapon in a honor duel.
