Wow guys ... what is a "rare" item? For me, it is an object that can not be crafted, like engines, batteries, beakers. But I guess you're talking about new items. Which, by definition, are not yet in play. Because once they are there, they won't be new after one week. And players will start complaining that they can't find them. And TFP will put them in the craft list. And it's a vicious circle.
If you know how to play, you find everything. I played a lot in multiplayer, and I mostly saw players who don't know how to explore.
Complain that you have no reason to search the POI AND that we do not find enough stuff, it's also stupid that paradoxical.
If drinking water was an extremely scarce commodity and could only be found in well-kept POIs, it would be exactly the same.
Solo play is my concern currently, and we can find everything too easily. In my first post I wanted to know if setting a 50% loot for example had an impact on what we harvest with wrench. If yes, I'm fine with it. If no, there's an issue with the perk.
