No it's not the complexity, it's the time available to the player. I switched to Rise of Flight partly out of frustration with BS/FC2. The online experience with that combo required a large time investment often with little action to show for it. That isn't to say the the experience wasn't great at times. I can recall a handful of really gratifying online sessions. With Rise of Flight the multiplayer experience is extremely up close and personal. The fights are almost physical. After half an hour on a populated server my palms are sweaty and my heart is racing. And after an hour I can walk away from my desk and return to my family completely satisfied that I had a great time. IL2 is a similar experience. So while I have loved first Flanker 1, then BS since it's release, and am learning to love the Warthog, these last two will now be single-player experiences for me. I can fully "comprehend" a half-hour flight pre-brief followed by a 1 hour coordinated CAS mission with comms and SPI handoffs, I have zero desire to invest the time when other aspects of life take priority. It's basically a question of time invested online vs the joy of the experience.
