As many folks know when you enter second wind you cannot leap or climb so you become much easier to chase down and kill.
well a good tip i have for everyone is that most of the maps have a river of some sort. If you run through the water you leave no neon green blood trail. This makes you much harder to track and follow as you can run the river as long as you need to to get away then exit to heal without having left a blood trail. hope this helps some of your plays!
