TLDR: It seems something HAS changed, as always things that involve RNG can have very skewed results and confirmation bias. This post might be both of those things, but take this info as you will. It seems loot overall in previously "HIGH LOOT" areas has been toned down, still spawning goodies, but not as much as usual.
Testing step by step:
*I only loot lose loot, never searching any containers, this might be tested later.*
1) Start by hitting power
2) Idea Office, Idea Resister tech spawns
3) ECM tech spawns/med loot
4) German tech loot
7) Texco (Also tech spawn near the PS4)
9) Ultra med
10) Dark room next to Ultra Med
Now I've ran interchange a lot this wipe. So I have a good sample size in mind, before this change whilst comparing. It seems as though, the amount, and quality of what's found is less. I did find a GPU on run # 5 in Techlight, so it seems they haven't completely removed high value loot, like fence might suggest. Take this with a huge cube of salt, because as I fully understand 6 is a incredibly small sample size.
Noteworthy things I noticed: Kiba is absolutely shit, I looted Kiba every single time, and sometimes it seems based on the screen shot I didn't even hit it. I only picked up things you would normally pick up, ignoring shitty hand guards and default pistol grips.
I'm going to continue doing these runs, and update you guys here while I drink coffee on my day off and watch netflix. Feel free to post your runs on interchange as well.
ALL RUNS WERE DONE OFFLINE, I HAVE NO IDEA IF THIS EFFECTS THE LOOT POOL OR NOT, SHOW ME PROOF IF IT DOES IN FACT EFFECT IT.
