Idea Kill Players Instantly When They Stand on a Barrier Block

Using a checkered spawn block floor is not the most optimal way to make a kill floor in maps. I suggest having a specific block that will instantly kill players if they stand on top of it like standing on enemy spawn. The barrier block would be a perfect candidate since mapmakers usually use them to block off roofs and other high spots that only soldier could reach, and if by chance someone actually reaches the top of those barriers they will be killed.

 

There are a lot of maps that like to place barriers to the world build limit on roofs of some buildings. However it's very difficult but possible to block glitch to the top of those barriers. If this feature is added, it could also punish ninjas for trying to pearl through barrier ceilings/walls.
