BF4 is introducing their deepest online career ever. They're also tweaking it to make it rewarding for newcomers and challenging for returning veterans. While sharing similar basics with Battlefield 3, they are now offering a cleaner upgrade path, clearer Ribbon and Medal progression, and an increased focus on richly rewarding team play! If you get a few shots in on an enemy but can’t manage the kill, you’ll still get awarded the kill if that enemy is later eliminated. The thought here is that if you’re contributing to your team you should be rewarded accordingly, since team play is crucial on the Battlefield. Team play is one of the defining aspects of Battlefield 4. And with the new Field Upgrades system, they are making sure to reward team play specifically within your squad. The concept of handsomely rewarding great team play is also highly relevant for Commanders. Scoring in itself is one of the major ways for Commanders to verify that they are making a critical impact in their team's struggle on the Battlefield. The scoring system effectively allows your team to influence all aspects of the Battlefield. From team play to playing the objective and the more strategic aspects of the game (such as the Commanders receiving points when their team uses the Supply Drop provided). Overall, the scoring design in Battlefield 4 is meant to make everyone willing and able to contribute to the greater cause thru teamwork.
