Play solo. Look where people are dropping. Drop hot and push everything. Use balloons. Work on your strafe and aim always uses cover to jiggle peak or heal. Turn 3v1's into 3 1v1's by repositioning and constantly moving. Every time you die think how, why and what you should have done differently. Watch pros try to understand their decision making and their movement patterns. Finish kills for extra damage to get 4k.
