Tentative +1
Used to hate this, not as a mechanic, but because I originally came from PG and I thought that the addition of CLIMB_SWEP in stuff like tryouts was a stupid and unnecessary thing that people needed to learn to advance in a roleplay server. Too often did it over-complicated getting into certain positions (RC before their revamp, Green Company, ARC troopers) because they would judge you based on how good of a climber you are in some crazy complex course dupe rather than what you could offer in terms of RP.
But I can see it as advantageous for situations in which you need to use a grappling hook or something like that and it does beat b-hopping. It is fun, don't get me wrong, but the server needs to be careful that they don't get obsessed with it in terms of advancement.
