I taught a friend of mine one of the Karachi elevators. Really, the guide here is what helped me the most (especially with the evening out of the lines). The easiest one to do is probably going to be that Karachi window one. Favela is pretty easy, too, for the most part. Once you’ve gotten one down, they start to get much easier.
Personally, I need help with jump elevators. I cannot, for the life of me, seem to get it to work at all. *sigh*
