Keep the /pk home commands to alleviate kwagscraft's problem, but ditch the coal/redstone blocks.
I really hate the way City works now. It used to be you could do any levels over once a week, and the lower levels paid you something worth earning. That was really helpful to me as I learned City, and now that I've mastered it, it's fine, whatever. But I see new members who are stuck in just one level for forever, with no incentive to go back and redo previous levels, and that's just way less fun.
And I'm very annoyed at how my home in City randomly moves, and how any death in any other parkour brings me back to City. Or how I have to relog just about every time I finish one in order to get paid. It's just awful.
