The cavalier will have a couple of mount-related bennies, but they will NOT be the main point of the class. The main point of the class will be to have a martial class with a more “social” class skill list, ally-boosting “berate” powers, and most likely some cool abilities tied to one of several “allegiances” you can choose from. All will be revealed in the Open Playtest (and in truth we’re still developing the class), but we’re well aware that horses don’t fit in dungeons and make a totally lame anchor for an adventuring class.
There’s also a LOT more to the oracle than predicting the future. Indeed, that’s going to end up a relatively minor aspect of the class, which will be a “spontaneous” divine caster. We’re really excited about this class.
When we get back from Gen Con we’ll post short summaries of our thoughts so far on these classes, so you can tell what we’re shooting for. The names suggest the conceptual niche, but it’s really important that these new classes have a _mechanical_ niche as well, and we’ve come up with some really exciting ideas I think are going to blow people’s minds.
