After a couple games the ladders do become quite annoying. Simply because your dungeon gets bigger and higher level and you are not talking about chasing just one or two ladders. They appear three to four at a time.
Teleporting a squad onto a ladder does nothing because they do not attack it automatically, which is lame. Even then the clunky user interface requires you to select the squad you just teleported then another order to attack them.
The clunky user interface makes it worse if invading adventurers make it into a room, simply because you can not teleport your squads directly into a room, you have to teleport them outside a room. The rooms have such low hp that you ussualy lose the room.
Ladders also make traps pointless because ladders can appear anywhere bypassing the traps.
My last game I think adventurers came in through the front door once. Probbaly becaus eI was letting a ladder survive to harvest heroes. SO most likely if you destroy all the laders they still come in through the front door.
