If the only purpose of a ladder to you in Dark Souls was to kick enemies I think you didnt understand how much insane amount of time they saved you. Most useful things ever... lol, that and they are awesome for when you dont have space or logical reason to put an elevator or stairs (which can happen a lot, specially if you are trying to create a particular feeling).
Ladder = incredibly useful.
100% right, I'm always going to go up after the Miqotes. :D
