I really really like this. Scratch that. LOVE THIS. I currently have all bis items in game I want and 1.1b spare cash, once I max cape and inferno there's not going to be anything to do, but with boss hiscores I can actually try getting a rank on a boss. Bless anyone with 5b+, Max cape, etc. Because there's not much to do other than staking at that point, so this is a great suggestion.
