actually i would like to know how much theory helps in the overall mastery of guitar. Would playing songs via tabs suffice over years or at some point we'd have to stoop down and study theory in order to progress?
It actually depends on what you are heading for in the end. Usually a musician's goal if to achieve pure expression, in the sense that you could play what you hear in your head without relying heavily on theory knowledge. Tabs are pretty much shortcuts to play a song, and it does help in training your ears.
But imo, knowing how to play without theory knowledge is like having an ability to speak a language but not being able to write it. Theory helps you understand what you're playing & with a strong foundation, the music you hear would make sense to you. You won't be just hearing a 'group' of notes, you would be able to make sense of the melody, chord progression etc.
Whether it's important or not to improve your playing, I don't know. But imo, never treat theory as a boring thing, think about the things that you would learn from it, the more you know, the more exciting music is to your ears.
