I agree. Also my family, which includes 3 kids (7,3,and 10 months now) rarely get a 4th FP. I understand that many of the headliners FPs are gone by the time you get to the park. However, we usually do our 3 and maybe a RS (often times we forego the RS because the kids are ready to go). Most families are getting more FPs than us even with the RS. Also, we typically book FP for everyone who can ride the headliner and then something small the too short kid can do. If the headlines is 7DMT, we are booking that and usually Winnie the Pooh or Tea cups. Those FPS are easy to get.
Honestly, I'm looking forward to the days when we can all ride everything together. I'm certain we will all get to experience more attractions when that day comes.
I don't think I am getting anything extra with RS. As long as Disney keeps its policy the way it is, I intend to keep using it that way. We don't use it to break tiers mostly because each park has a headliner that is a tier 1 everyone can ride. We book them all for that...ie Frozen Ever After, Navi, etc. At AK, we booked everyone for FOP given this discussion want their to be any issues with us riding it. Now we can each ride FOP with the FP and get two RS tickets. We won't do that because of the amount of time it would take. That would be unfair to our two younger children who enjoy doing other things together, but we could. I agree that would be excessive, which is why we typically book one set of FPs for the headliner and then something else the littles can do that is nearby.
