Super efficient, fast, easy way to improve your K/D.
What you'll want to do is stay in the plane till it forces you out, then either stay still to improve your chances, or go towards the nearest town. If you stayed still, then when you land, you should be around 3-4 AFKs, then just punch them all to death, then go collect. If you decided to go to a town, then get some guns, gear, then go back and kill the AFKs (Bigger chance to not get kills because some other people might stay there and get the kills for themselves)
