I must say, my best scores are on a team that plays the objectives - AB&C and with one guy causing a diversion at G or E. When I'm on a team that doesn't follow the squad leader's orders, I always have a low score with low kills and high deaths.
Well, my primary objective in the map, is being a disturbing force for all the infantry and armor close to ABC
Then and only then, i do follow the orders to defend the flags, unless the other team dunno push the limits of my team, and i move to capture the flags by any chance i got
I tend to go for points first. While everyone is scrambling for D, I'll stop at G or E, get 500 points, take the LAV and either (dare i say) go and get another 500 points at F and then see what's going on at D, or go directly to D and get killed.
