Sadly yes
ManofWar is the only player I've never beaten in duel. And there was a period of time where me and saul went 1:1 in duel :/
I have a mental block vs him, when I was still relatively new, like two months into the game I met him for the first time. I was not a bad player, I did well in battle/duel and was good at chambering already.
It was a duel tournament i think held by kalam. Manofwar gave me a special condition for beating him (I was a nobody). He said if I managed to HIT HIM TWICE he would concede victory to me.
I never hit him a second time in 4 duels.
fast forward months later, I never coped with his fighting style and I dueled him so rarely, that I have never beat him.
I don't get it. He broke me.
And I've never lost a duel to rhade, so whatever.
