These are the changes I would make to the kits:
Samurai: First thing I would do is make the diamond sword a stone sword. This is the second most damage dealing kit. I would then make the protection 3 to prot 2 and also change the feather falling to feather falling 2 or 1. I really hate the samurai because they hit you then run away and you cant chase them because of speed. The only way to kill a samurai is for them to be determined to kill you or you combo them.
Warrior: I would only change this kit by making the sword sharp 3
Beast: Maybe add some feather falling or prot 2 on the chest and leggings
Wizard: I would probably just get rid of the speed pot
