Awesome, we can't even get admins on the same server to agree to a standard enforcement. So basically players have these options if they are the last one or one of a couple:
1)destroy the ladder, possibly kicked depending on admins present
2)climb the ladder and likely get pin cushioned one by one
3)wait it out on the ground and get accused of delaying/camping and get kicked, depending on admins present
Once again, the terrorists win.
I would personally volunteer to change all the maps on the NA servers to add barriers and/or permanent ladders and make sure they all had flags. I make maps and barricade 90% of my roofs, leaving at least one permanent way to the ones left open. I don't believe ladders should be removed completely, as much as I hate archers. They do provide some interesting tactics occasionally.
