Guild Wars 2

I would like to suggest that when a trap is tripped there is a ping on the map that your server can see.

Would it ping for just one player who runs across it? Or does it require a “weight” threshold (like the difference between white and orange swords)?

Well maybe not a ping but maybe an icon that is on the map when the trap is down and it will do some type of alert on the mini map and give you time to check the main map to see where it was tripped at.
