Most other subjects, I'd say classes are a bit sub-optimal, but still a great choice if you aren't working with unlimited resources. There's value in hands-on group projects, labs, instructor feedback, etc. And, in most subjects, there are plenty of successful people who did a lot of their learning in a classroom environment.
Language learning, though, I'd say that a classroom is worse than nothing at all, if you're motivated. And not just a little worse, like, a lot worse. In language learning, it seems remarkably consistent that the vast majority of people who achieve much success eschew classrooms entirely.
