On my own I gain an average of 200-300 a day. However, I find my biggest increases come when I am on good teams. When I am in a group that works well together the points just roll in. Whether I play a combat class with good medic support or actually play a medic, it makes all the difference if the team works together. Even if I am working with another really good player and the rest of the team is all doing their own thing I won't see near the success. Teamwork, teamwork.
