From your personal experience up until now, how many core classes would be efficient to play so you would not need any extra time spent grinding? E.g: focusing on only 2-3 classes so that they're as close to your main level compared to focusing on 5-6 classes and having all those being eight levels lower than your main level unless you spend extra time that you wouldn't need to if you did the former.
Also, not a fan of that field of depth thing going on in the background. It's like looking through the eyes of someone that's short-sighted. Which I don't want to admit is in the process of happening to me.
