I understand it's just an idea, but adhering to your idea you should have more set options for each class, as there are many magic classes that don't heal based on HEALER's spells like Warlock or MAGE. Type a damage bonus to cloth, light and heavy option. Because, moreover, there are many people who create such classes focused on damage, or tank or sup, although they were made for the respective areas. But the game is so wide that you have a huge possibility to build a BUILD and be different from the other, thus making an immersion in what concerns "strategy".
