Repairing gear at a Repair Station is meant to be for high tier gear, like the ranked gear that you would get from Supply Crates. Any other “free” kits can essentially be obtained again within the period their cooldown ends. There is a 30 second cooldown for Kit PvP and a 5 minute cooldown for Kit Zodiac. You can also use /kit in combat to get new sets, the idea of having gear that breaks at a frequent pace is to add an additional aspect to the PvP mechanics, keeping an eye on your gear constantly. It is actually a good leverage tool for players in default gear to win against people in ranked gear like Reaper. The Repair Stations are also placed around the physical map so that way players can repair on the fly, mid fight. So let’s say you have a Reaper Scythe, which would be worth the $2,500 repair cost, you can lead your opponent over to the Repair Station and fix that without having to leave combat.
