Runner tips from a hunter main
Some key mistakes I see over and over. The runners that adhere to the listed things are extremely difficult to combat in my experience:
Heroics: rushing a body or a sacrifice when the hunter is guarding it with both turrets is a recipe for death. Cap a node, make him pay for that kill. I can't tell you how many times I've had an early win because I wiped 2-3 hero's who rush right into a trap.
Divide and conquer: cap multiple nodes at once. This is a worst case scenario as a hunter because it guarantee you'll get one as the hunter defends the other. It IS TRUE that more runners on a node=faster cap, but it's not worth the risk of getting multiple people down when the hunter shows up.
Getting fancy: all those fancy jukes that don't create distance is exactly what a hunter wants you to do. Eventually his stamina will recharge and you'll get stun-shotgunned.
