This pyramid on Daraman definitely needs to be reworked somehow. There is no protection zone on it. However, if you get to the top floor with pz-lock you can no longer jump down. You are stuck there just like the floor below is protection zone even though it's not.
I don't think there should be protection zones in spawn, and a pyramid like this is too overpowered to be able to stairjump. My suggestion is that you make the pyramid only one floor high, and with a flat roof, much like the ankrahmun shops north of depot. Could add some obstacles on top of it aswell. Stairjumps on pyramids is very annoying when trying to kill people :)
