Reverse tree question?
So I am considering having a go at the reverse tree, but will that wipe my progress on the Spanish tree?
No, it shouldn't wipe out all of your progress, but if you stop strengthening skills altogether you will find that you've lost strength in several of the units. I'm doing the English-Spanish tree right now. My Spanish-English tree was completed and all gold at the time I started the English-Spanish tree, and I just checked and I've lost strength in several of the Spanish-English tree units.
Yes. If you don't use it,you lose it, but not all of it. My En-Fr, which I have not touched for the last year or so is at 18%. I did Immersion work during that time though and I am not sure whether it was tied in. I don't really pay attention to the levels as they are not indicative of the work I do outside of DL AND they apply only to a select few languages.
