Imo the health packs should be at two places in both sides, on top of the island and at the beginning of the low route. Not only would it be more convenient for momentum, this way you can both push and heal yourself without having to make a U-turn and trap yourself in your own base again just after countering one of several incoming spawn raids. Also when the kits are on different places it's harder to drain them all out at once. To make this setup or any item placement setup in general more efficient it's up to Soldat to have a reliable and organized spawn system for items in the future versions.
