Completely agree, when Duolingo started, I took the Spanish course and actually got something out of it. The lessons, comments were super helpful. I've tried it again last year and I couldn't believe my eyes that most of it is gone. It feels exactly like an addictive game, making you focus on the game part of it, not learning. And the fact that you can buy out of failures is just WTF.
Same, I now speak fluent Spanish and have lived in Spain but I started with Duolingo (although just watching loads of films was by far the best way to learn once you get that far!).
