Well, I've recently been using spectate, a lot, and cycling through plays gets vigorous and some times the player your looking for is dead, so I came up with an idea. What about a better map for us? It would help with player finding, but it would require a lot of work and a option to disable the "DEAD" area, or have it transparent, but none the less.

This is what I think it would look like, maybe have the numbers inside the player, what ever works best.
