I think it would be neat if they added in two classes that work the way Arcanist does, basically two paths.

Soldier would use Great Sword and could become a Dark Knight (DPS) or Rune Fencer (Tank).

Ronin would use katana style weapons and could become Ninja (DPS) or Samurai (Tank).

I understand though that Ronin is probably a terrible name for the starting class, but I literally couldn't think of what else to call it.
