Not only should Leaf get a weapon, every village should have multiple weapons and weapon specialization masteries. The game desperately needs a way to add variety to builds. Right now the only serious hybrid options are WMs. Sand's 40 Int WMs with a Crystal Fan switch is a good example.
Advanced will be a big update that brings lots of new options, but given that the precedent for tools is already set, I think it should be looked into sooner rather than later.
Off-topic: There's about 2-3 hours a day where the whole server is dead. 4-6 of prime time where every village can be active. In the remaining hours only Leaf, and sometimes Takumi Orgs, can put together a larger group. 3-4 vs 8+ is a frequent occurrence dealing with Leaf outside of prime time.
What's the deal with Leafies catching amnesia and forgetting they had a numbers advantage after every fight? Ya'll have consistent numbers. It's not a bad thing necessarily, but you do. 8 players, two of which are AFK, might not seem like a lot but it is when the other villages have 3 players between them.
