First of all idk where u got that number from but that's cap in a 20v20 only like 1-2 ppl would get Wof
Second yh leaf could use some communication work but don't study our things
Third We don't want something necessarily stronger but at least a weapon as well
Forth this point late but the balance you spoke our between villages both mist and sand have good stuff but yet leaf doesn't
Fifth if fan without wind is not good why 90% of sand rocking a fan and ik for sure only like 45% are wind
Sixth you don't see a problem because your village has a weapon and the best passive in the game, let's not forget your Jonin's not as buggy
