It's simply that the hard way is also, by far, the better way. For instance, the language of magic in Lamorre - I could not learn it this way, and then practise magic as I do. I must be able to think in those words. I must have a deep understanding of the language that you simply will not acquire in such a - a surface-level education.

It is a beginning, that's all. To rely on it entirely - to not practise, or develop further - is to risk losing all nuance in translation. It is lightly overlaid, not deeply stitched.
