The name of the classes are correct but Famitsu has thrown a curve ball at the predictions of your proficiency.
It appears that the Authority proficiency will stay with the Lords and it's "promotions". Additional weapons are given to intermediate classes which would otherwise have only one. Reason users also use Faith.
I still got hopes for the following classes:
War Mage/Mage Fighter (Reason, Faith, Sword)
Mage Knight (Reason, Faith, Sword, Lance, Riding)
Baron (Reason, Faith, Lance, Axe, Heavy Armor)
Mage Flier (Reason, Faith, Sword, Lance, Flying)
