I play battlefield 4 a lot (like over 800 hours) and I've come to like 2 classes; >engineer: I mostly play conquest or rush and in those game modes there are a lot of vehicles, I run engineer so I'm able to help take them out. Plus I'm an attack chopper pilot cause most people can't fly at all, its better to rely on myself to repair my own chopper/vehicle. >medic/assault: I mostly use this class when I play on infantry heavy maps or I'm sticking to indoors. Many people don't drop medkits or make good revive calls. Some don't even fulfill their role as a squad medic. So I try to pick up the slack or be MVP of the match.
