I very new to this game. I only played for about a hour. Now I not understanding how this classing system works. I a revenger now. When I get to choose my next class will it build from my previous class, or will it be its own class (like I need to level up 2 separate class, and swap between the classes.) Now if one build from the other it makes a difference in how I build my character. I do understand your first class dictates what classes you can choose later.
