One of the very first RPGs that I played was Final Fantasy for the NES. I remember pouring over the manual at my friend’s house and becoming fixated on the concept of how characters would transition from their starting class to an advanced one when they “grew up” in the game a bit.
Classes that evolve or change into entirely new ones is something that MMOs have dabbled in from time to time, including the old version of EverQuest II and the upcoming Guild Wars 2: Heart of Thorns. It seems a tricky line to walk with established characters, because while a new build can be refreshing, it can also disrupt the satisfaction and stability that the class used to deliver.
Do you like the idea of advanced classes? Should more MMOs add them?
