Kind of a badly implemented challenge at this point in time. Ive completed hc vagrant warrior in turtle and that seemed more fun as even at lvl 50 you still had one weapon upgrade from DMF to look forward to. But in this case you only have a random chance to acquire a better weapon than a level 35 weapon. Even that white piece of meat from DMF has a higher dps

well i guess having green armor compensates for it but still im supposed to be a samurai not a vagrant
Also i know im getting into real fedora territory here with m'comment but proper samurai from the war era were trained in pretty much all the weapons and bow was one of the most important one. They were basically simply warriors. Having thrown weapons allowed and not bows kind of sounds like some ninja fantasy and not really samurai. I UNDERSTAND however that we are in this case in the game we are supposed to RP the peace era kind of "ronin" wandering samurai, but even they had some kind of tanto or wakizashi that are short swords and in classic wow we have this kind of dagger that looks exactly like those so why arent those daggers allowed? And also if we are supposed to be thinking of those "ronin" type of samurai then why is wearing plate allowed when those were mostly worn on the battlefield, and there those samurai used bow and spears and daggers too....
I know i may go into too much depth here and overthink this challenge but adding some or removing some restrictions really shouldnt be that much work as adding new weapons to make the challenge less grueling... just some ideas... jeeez im such a nerd...
