A number of points actually capture what was going on with the system:
Jumps were always meant to increase your jump height by 1-4 blocks high and the descriptions explained this in the original update. However, there was an issue in the system were you were actually jumping double, if not more than that. Watching people getting to the top of the world in 30 seconds isn’t the intention of the system, nor is the system meant to replace grapples or make combat massively easier because you can jump out of the way over everything.
It seems most of the negative comments towards this change is around the need to use grapples and the amount of skill points it costs. Grapples do feel like they need more attention on this feedback and the jump skill cost needs to be reduced. Also, there is a skill which will make your character a torch so you’ll be able to light up the area without holding a torch.
It does feel like players had access to a godmode and we took it away and they are upset. If the original implementation was correct there would be a lot less resistance to it. It would be interesting to know what new players think of the current version.
