I have played a number of duels. I don't know what the algorithm is for figuring out which spawn point to place the freshly killed player but it's not working if the intent is to place the player away from harm. On Shangri-La, Many times I would get killed around the two lifts to have a spawn at the rockets. I have no chance. Same thing has happened at the shock spawn when killed in that room.
Anyway, I suspect that the algorithm used for determining spawns needs a closer look.
