Surf Combat - Auto beacon at final 30 seconds.

[Sir Lagalot]

Or perhaps add a function that beacons players that do not move for an extended period of time, that doesnt disappear until they have moved a certain distance or something along those lines?

I am against this part of the suggestion unless it is for only the last 30 seconds or so of the round.
I am also not too sure if I support the idea as a whole. Sometimes I find that servers that have a whole lot of features like this can become annoying and boring. If someone is purposefully delaying (e.g. hiding at the teleporters at the bottom of great river) then you are allowed to tell the enemy where they are.
