If the feedback on this is based on feelings of realism, I could make comments on the use of gold alloy as tools for labour use...
I can understand your/havok's point, but I did always get more of a magical vibe from the game than a technological one... I guess in my mind it's a magical universe because of the way it looks, I don't know. And even then, the Predator from the Aliens/Predator universe can jump many meters high.
I don't expect there will be any sort of flying, although I've seen jetpacks mentioned I don't believe that's a confirmed feature and it would overlap with the bonus provided by a jump ability (depending on how it's implemented).
But honestly, if there is a good compromise for moving around vertically, I guess I would accept it - like I said above, for me it's a useability issue, mostly. The auto-reel hook sounds like something I'd be happy to use. Anything that improves vertical movement but doesn't feel fiddly or clunky to use is fine. But if jumping over 2m high was too much, I don't even see the point of having the jump skills at all.
