There is much to process here, but some comments...

• paladins are traditionally Knights rather than Soldiers
• deathknights seem like they should Knights rather than Soldiers
• Mercenary, Monk and Assassin are existing creature types and clash with this list
• Soldier Druid and Warrior Druid both share title hunter

I cannot tell if any of these are problematic or what problem this list wants to address.

Wizard druid would be a biomancer

Nekomancer.
