I like the idea of no metal base parts dropping from animals or in crates. They should only be in supply drops where you would have to research and resource to be able to build a good metal base. I'm not sure how the loot tables work, but if it were only a random piece of metal building, and a chance of c4/grenade/Kevlar it would add a bit of difficulty. Having the starting MP5 and being able to loot MP4s, ammo, med kits, food, and lesser armor from the crates/animals would keep a PvP feel and allow starting players a place to farm some gear without making the game too easy. There has to be a reason people raid bases to get peeps gear otherwise people just build bases nobody wants to expend the energy to raid because it's easier to get the stuff from animals and crates.
