I myself love to do PvP. PvP has its ups and downs, but the "down" I am going to focus on fixing is Spawn Killing. To tell you what I am talking about I will give a common scenario.

Myself and a group are playing FFA (Free For All) and I die. I spawn and... BOOM dead again.

My idea is making a tunnel starting. This tunnel where you spawn and you walk out of it when you want to compete. There could be a radius of 20m or so around the tunnel where the opposition can not walk in and just spawn kill you out of the tunnel. This idea may not be good, but if there is any suggestions for finding a way to stop spawn killing it would be very... helpful
