Upcoming MMO: Ashes of Creation

>64 unique classes

dead on arrival, no one can maintain balance in something that big

Agreed at first glance it looks like a pretty hefty task. However, this class system does not exist as 64 classes all with entirely different skills. Only your primary class will have a basic skill tree while adding a secondary class gives new flavor to those skills. There are no new skills with the secondary class, just augmentations to fit what type of playstyle you want. Secondary classes add attributes akin to the primary class as well: Rogues are adept at finding and sensing traps in dungeons, with a Rogue secondary you would gain some part of that ability. Obviously we won't know much about balance until testing a ways down the line, but initially it seems this won't be something like LineStory where you cash grab to upgrade weapons and such. At least that's what they're promising. We'll see what happens in the testing phases in the future..
