Here’s all I remember seeing about classes. Seems to me that they were trying to differentiate between classes and careers because there are tangible differences between the two: customization instead of distinct heroes (a core competency and much-loved feature), cosmetics shared between them (unlike careers), and who knows what else. I don’t really get a “more than” vibe that insinuates a talent tree, and the class-a-quarter was stated, so who knows.
