This was discussed in the Blockland r1908 thread a while back, I would like to revive this discussion.
For those wondering, this is what I'm talking about.
It causes players to easily exploit any sort of map, and has become a problem on several of my servers.
Why don't I just have some sort of block on the top to prevent them from doing this?
It's a real pain to have to make sure your map is exploit proof, I could be working on improving the map rather than fixing stupid exploits like this.
It's a good use for challenges!
I agree, it adds a challenge to those games, but there are games where doing this gives an unfair advantage to some players.
