Yeah, I have seen it on other servers as well. It's not ideal but basically functions like this: in climbable locations, you can use your climbing gear and you are ported to the next level up on cliffs and the like, though it could be used for longer descents/ascents where applicable (situations like the wells that lead into the Vallaki sewers, for example.) I think it's a cool idea to implement, since we have rope in-game and little use for it other than RP (as far as I know anyway.) They already have grappling hooks and rope with grappling hook items in the CEP, so it would just be a question of adding these items into the game and scripting a system. I imagine the scripting would be rather time consuming and a giant pain in the ass considering it would require adding all the locations you can climb into the game. If it were to be implemented though, I suggest borrowing from Age of Conan and having an environmental text pop-up "you can climb here" or something to that effect when you're in the appropriate location.
