Slope jumping didn't exist in 1.1. Yet it was still possible to get to all those locations. It used to be challenging

. Tho I'm glad humans (and rants) got a bit more mobility, I just think this is
a bit way too much and makes it way too easy. Also 1.1 maps weren't designed with this in mind, and thus it creates many unintended and gameplay changing ways to move around, for example the Nexus6 alien base. I guess that location is no longer very good for aliens in 1.2 (was the only very good location, don't remember any good player ever intentionally moving), as a saw can get everywhere very quickly (used to take luck and effort or a good lucijump).
About the other posted locations:
Niveus boxes with a rep+ret+armo, might be possible with just a rep and a teammate.
Transit human base crates with ret (same place as yours) (same starting slope->low crate->RC->high crate->ret->other high crate).
The WHOLE Transit high ledge was/is accessible with a double strafejump.
Nexus6 alien base: slow, but possible.
Karith: most locations the same way, except pipes required way more building or a teammate and some building. The pipes *used to be* my favorite building location, because, again, it *used to be* challenging.
