What is wrong with having quick pit stops and refuelling!?
It encourages "cookie-cutter" strategies - no-one does anything desperately different any more. The races just get broken up into basic sprints between the stops.
To their credit, Schumacher and Ross Brawn used to mix it up on occasion. In 2004, at the French and British GPs most teams stopped a total of six times - three in each. Schumacher stopped four times and twice respectively, and won both. But it would be nice to being some of the old strategy games back, where fuel and tyre management was actually critical.
