Maybe change holy knight to paladin and then paladin to just knight because the holy knight,to me, sound exactly like what a paladin would do(although in my mind a paladin would be sword in shield but thats just me) and the paladin(normally a paladin would be a holy/blessed knight who heals) sound exactly like what a knight is. Also maybe the knight can use any one handed weapon plus a shield. Unless there is going to be a specific class added in the future which is able to do that.Also I like the fact that you got rid of clerics using maces. Another thing Samurai sounds like it would be more inclined towards strength considering any Samurai I can think of wore what looks like(from pictures) heavy metallic armor which to me makes sense considering how big their swords were. Take that with a grain of salt because I am by no means an expert on Samurai at all. Now Swordsman could be your agility type sword class that focuses on speed where as Samurai because of their heavy armor(which probably makes any move they make cost more stamina/energy than a swordsman) would have to deal with their opponent with as few moves as possible hence the high strength aka more damage. I also like that you gave ninja a dedicated weapon versus them sharing one with the assassin. The class descriptions are also very appreciated though I cant recall if you had those in your unedited version.
