Notes:

Back in Update 16 and before that, Coptering was the best way to get around maps quickly. It was basically Jump+Crouch+E, and the faster your weapon was, the better you could copter. The Tipedo had the fastest attack speed at 1.3, and when combined with Berserker, you could go from one end of the map to the other. Update 17 removed it with Parkour 2.0, so no more coptering.
