There are 35 other characters that you can go for that are open. Now that side kage are just kage now, with their own jutsu, there are plenty of other clan options you can try.
I’m not interested in adding a subset of characters to the server for players who aren’t trying to play the game how it is supposed to be played. A character is only as difficult as the kit you choose in application to the character testing criteria. If you can’t play your kit, you don’t deserve the character. There is no arbitrary difficulty, it’s very literally dependent on your choice and how often you practice and try to get better.
