So Over the last two days I have run into alot of new players mostly kids.
So if I rip through them in the 1st couple of mins I ease up let the reinforcement. Try to play more stealthy and hunt them rather than obliterate them and make them never want to come back.
If they have game chat at they actively talk to them. Tell them to stick with there team and try not to camp and complete the objectives and so forth.
Anyone else?
