My favorite class has to be Valkyries/Mage Knights. I always lean towards magical classes and Sage comes at a close second but I have always loved the idea of a mage on a horse (if we are ignoring the Tellius Valkyries). While you can make the argument Dark Knight is basically that too, I find staves a lot more useful than swords. Not only that, Valkyries have great movement like all Cavalry classes and I find to always love their battle animations. My only flaw with them is that they promote from Troubadours,which aren't the easiest class to train up and they usually don't have the best growths making them ehhh in combat. But even then, having a mounted healer that can defend themselves is amazing, I just wish they just got rid of Dark Knights and made Valkyries the second of the branch promotion for mages so we can have more offensive oriented Valkyries. I also love their designs.
