You only like classless systems that force you to pick separate classes? That's funny.
Yeah, that was precisely my point:
I don't think "classless" systems are inherently a plus and in fact I like them only when at the end of the day lead to the same result of class-based systems... Mutually exclusive choices offering sensibly different playstyles.
I also dislike class-based systems that don't offer enough differentiation between classes, incidentally.
If you are finding this "incoherent" the only explanation is that you didn't get the point I was making.
