I was actually quite effective as a "lone wolf" in Battlefield 2 and 2142. During many pushes I was with my squad -- but a very large portion of the time I was either capping very obscure objectives to split the enemy up, screwing with their supply of vehicles, setting up annoying traps for enemies (c4 under bridges, double claymore near heavy jeep routes, etc), or taking down high-value targets that my squad would complain about. When they needed me I was there of course -- but during a very sizable amount of time I was professional shit disturber... get in the enemy's head... keep their jets, walkers, and tanks dead or our's... etc.
