Edit: I am so sorry. After doing this myself I somewhat agree with OP. Getting to the top of the tower should have been where the sightseeing point is. That alone was enough of a pain, given all the invisible walls in this game. Jumping off onto the lamp post is just poor game design. Apparently SE didn't learn a thing from the player reaction to the notoriously shitty North Shroud jump.
Challenging is one thing, but this kind of indifference to the limitations of the game in regards object hitboxes and precise positioning is just atrocious design.
