Me too. The only issue with 3rd classes is the skills that 3rd classes bring to the game
If they actually balance the skills, it might be okay. As long as they come with content that's meant for those classes as well. Like if you drop 3rd on the game without higher level content--and with the skills being the way they are in chaos, it'd be a raging dumpster fire. Even without OCP they can be pretty overpowered depending on the class. Things would have to be adjusted. I think that's the point of this whole thread, because the big question is "how to adjust them?"
