Personally very guilty of spending a big chunk of my time rping with my FC, which to a good extend comes from the fact that my main leads it, and it takes a lot of time to get around to everyone. But I do RP with people outside of my fc, especially on my alts which are not so bogged down if you would. I do come with the downside that I am horrible at asking people for RP, and I am also not good at picking up on vague requests, so a lot of the times it's because people requested it - which I always follow up on, even if I am super busy at times. And I am always up for getting to know new people
