you will be able to farm lots of primos when we get inazuma next month, I say feel free to go for Kazuha
make sure to do the trial first and see if you find playing with him to be satisfying though
Honestly I love playing with everyone. I'm a huge Soul Caliber player so I love all the different play styles.
I spend a lot of money on this game, but thinking of just F2P this banner.
