I want to modify Spigot that my plugin can use an EntityMoveEvent to stop entitys from walking into other WorldGuard regions. I believe you have a reason(like performence) that you don't program an EntityMoveEvent. I want to ask you if there is a better way to stop entitys from moving into other worldguard regions. //Sorry for my bad english! I'm from germany....
I read that Towny does something like what you want. They use timers and then check for entities within a region and remove them.
