I honestly feel like Interchange doesn't have much of a purpose anymore besides food in the back of goshan, and industrial/hideout items. We all know about the lighting problem in the map (which nikita has said is a issue so hopefully it will be fixed sometime in the future), but it just doesn't feel like there is much reason to go. The main tech stores rarely spawn anything better than a tetriz every few runs (at least it seems like that to me, maybe others are getting much better luck for gpus), kiba and ultramead are a joke at this point with almost nothing good spawning most raids. I hadn't gotten the game when it seemed like interchange was much better, with killa not spawning in random places so there would be mass people to farm them (which can be understandably annoying to just have loads of naked vepr hunters), there being huge fights around killa in kiba, and really good tech loot. I remember seeing gameplay around that time before I got into the game and I would watch streamers go in there and it always seemed like a lot of fun to play. Now it just feels like a bad map with terrible lighting and subpar loot unless you are trying to farm the food/industial items.
