A very controversial way of winning island top is to 'surprise' the opponent by hiding value and placing it last second. While this is still within the rules, it is pretty unfair. You can simply get multiple islands to help you with value to overthrow the top island minutes before payout. It is simply impossible to come back once you've realized what has happened. On Factions, sharing value is not allowed. To prevent wilderness farms and hiding value, there is a points system. Basically, the more value you have in your faction, the most points you get. At the end of the week, the faction that has the most points (not value) wins. Skyblock should have a similar system implemented. This will encourage players to actually show their true value, rather than just hoarding and adjusting how much more you need.
