On other survival games servers, there are often chest refills. However, most of these are not a mere 5 minutes after the game starts. Some servers make the players wait up to 20 minutes for the chest refill, others are mostly 10 or 15. I suggest 10 minutes, which suits how open cubecraft survival games maps are, and how fast the games go.
This makes camping mid a bad option, as other players will have better gear long before the chests refill.
It also gives another incentive to gather at mid, before the borders push in. The border size reduction can even be delayed a bit.
Chest refills take some of the luck aspect of the game away, because most of the time survival games is about the luck of finding gear. Cubecraft doesn't have as many chests as some other servers, and chests contain fewer items as well. That means sometimes, most of the chests on the map could have been looted, and you still may not have full gear, let alone good gear. This will help those unlucky players and make the game more about skill and less about luck.
