I don’t mind the weapons being locked to their appropriate masteries but the way I see it is that it kinda balances things out since leaf, by default, always has more players in the village and even newcomers going to leaf. (Except for when there’s a new village). How is 10 pipe users going to take down 20 leaf ninjas? If you’re worried about other things such as tournaments and such, leaf has the strongest 1v1 mastery in the game. I’m not debating whether or not mist and sand have better utilities then leaf because they do. I’m only asking you and everyone to think about the balance in the game within standard population.
PS. If you want a weapon it would have to be a STR based weapon for GF which doesn’t make sense because of Pressure Point Needle
