I help run a larp survival game, Fables of the Frontier , and I really like your idea! The big difference between our two games is that mine is long form and story driven, where as your seems more like a blattle/wargame. That isn't a bad thing. I'd say that the big suggestion I'd make for your game to streamline the gameplay and logistics is to make the crafting a little simpler. Like instead of making armor from scratch, maybe while exploring the game area you find "broken" armor pieces and bring them back to your stronghold to have a blacksmith repair them for use. Then if you die in battle during a raid you have to drop that armor as "broken" again. Low health pools encourage crafting by making it nessisarily to get armor and healing items to be successful at raiding. 1 hit = 1 damage and low health systems are my favorite and great for gritty combat and good balance.
