Grammar translation v/s Behaviorism

I tried to learn a little Russian and Italian using just websites. Although it requires patience, time and dedication I did not find it hard enough to make me quit too easily. Furthermore, one must be really willing to learn if we ought to use this method. But as I compare this experience with the process I, personally, have gone through when learning English, it is much harder to learn on your own.
Grammar translation is important and when it comes to learning a language it is highly helpful, though it is not the only one thing we might need to fully learn and understand a language. This is where behaviorism takes an important part. Communication is the core purpose of any language, therefore, knowing a language implies the ability to communicate succesfully in different environments and situations. When we emphasize the grammatical aspect of learning language or even just focus on it, we are leaving completely aside the fact that in practical use we might not be very thriving students.
When I tried to learn Russian, I had the possibility of listening to the different sounds of the letters in my keyboard as I pressed them. This made me immediately repeat the sound once and again and then go to the next sound. On the contrary, when reading the grammar rules of feminine and masculine nouns in the Italian website I learnt nothing, not even now I remember what were the differences between one and the other.
Behaviorism is the notion that every physical movement or action -such as repeating sounds in this case- has an importance. In the learning process, this is why role play, oral interviews, or simulation of real life situations are so very useful.
It is not the idea to degrade grammar because it is important, I must say that its importance is only as a sort of confirmation of what rules language works with. It is equally important for conveying grammatical rules we may observe in language use, but it is not the main point of language learning. Grammar provides the structure, but actually using language is the best way to learn it.
