I will CERTAINLY NOT buff the NIN, it’s already a great class, potency increased now on ShB and your get a “kage bunshin no jutsu”. NIN is the most meta.
The dancer tho needs a buff, they can’t buff the weaponskills simply because they will be then FORCED to buff both dances or wouldn’t be worth to dance anymore. Dancer wont dance lol. They need a 50 pot for FD1 and 100 for FD3 and will be ok
