If you recruit from a geographically disadvantaged area (like the Northwest) in D3, it's almost a necessity to battle the Sims for quality recruits. Based on my limited experience so far, it usually takes a minimum of 2-3 Campus visits to completely turn a recruit green. But sometimes you can knock off the Sims by just sending a single scouting trip. Just experienced it recruiting in Dobie! So don't be afraid to battle Sims for quality recruits.
