[Suggestion] Make a second "Path of the Mage"
Half the fun of playing the game is using your sovereign as a mage. Magic plays a core role in the game. But only one out of five specialization paths really focus on this ability. That seems like a waste. I propose two mage paths: one with reduced mana cost and increased damage. And one which allows you to cast two spells in a round. Note that this is a high mana drain path choice. You don't get the mana reduction, and you don't get the damage increase.
For lack of a better term, "Path of the Sorcerer". Of course, it needs its own supplemental abilities.
