I don't understand why rocket jumping is so restricted on this map. There are extremely few places where it is actually possible to pull off good wallshot jumps compared to other maps. The map is geometrically cluttered which impedes mobility a lot. The art pass that this map has gone through has resulted in a very good looking map whose detailing negatively impacts gameplay.
These displacement walls negatively impacts rocket jumping. You need to be very close to a wall to pull off a good rocket jump (preferably 0 hammer units), but this is just not possible with displacement walls.
It is unnecessarily hard to pull off a good rocket jump from this position because of the fact that there is no wall to wallshot on. Also bad displacement walls again.
This wall is an example of a wall that you can use to get a good wallshot jump. I feel like it's way too low though, which makes it impossible to pull off a high rocket jump. Something to note though is that rocket jumps on angled walls are slightly worse so that's a downside too. The rock underneath it has awful geometry and it terribly unsmooth.
There are a few areas you can easily get stuck on the ceilings when trying to rocket jump through. This one is the worst offender, as getting trough the hole requires precision and just jumping towards the ceiling might get you stuck on the bolt underneath the ceiling.
There is a ridiculous overuse of displacements when ramps and flat brushes would have been sufficient. Displacements affect rocket jumps negatively if they are poorly used compared to ramps and flat brushes, as it is harder to rampslide on displacements but it is also harder to pull off a speedshot on displacements. They should be used conservatively. Even the roofs on mid are displacement for no good reason at all.
TL;DR: Rocket jumping is awful on this map.
EDIT: Additionally, this is a map where you need good rocket jumps to play efficiently because of the long distances you have to cover. "Harder" is also not the right description when describing speedshots/rampslides on displacements. It is harder, but only because it is pretty random whether you get it or not.
