Personally, I think other series that restrict the number of people over the wall have more interesting pitstops.
For me, the defining feature of NASCAR was the sound of five nuts being driven on/off during tire changes. I haven't watched NASCAR this year to see how the single lug pitstops sound.
I agree that NASCAR/IndyCar style stops with limited crew are exciting, but I also love seeing the army of mechanics doing an F1 pitstop.
If F1 had slower stops, I think we'd see much more uniform strategies, unless F1 wants to limit tire durability (which seems to go over poorly), or bring back refueling (which I agree is needlessly dangerous). Maybe F1 could introduce something new for pitstops? Allow larger scale aero adjustments? Imagine configuring a car to run on heavy fuel, then coming in twice to replace wings to reflect the lighter fuel load? Maybe the RBR would run better under heavy conditions, and the Ferrari catches up when lighter?
