////always seen playing in one position as one of my limitations but now I can count it as one of my skills.////

Well, it can also be a limitation if you rely on it in lieu of paralleling because you can't parallel. Paralleling has its uses. I want to make clear it is NOT wrong to parallel. Sometimes a chord change sounds better that way. Expressing tension or suspense or anger would be good calls for paralleling. It's just that we tend to parallel out of habit when chords could resolve in so much sweeter and musical a fashion.
