You do it automatically if you have a faceshield down or NVG + optic. You can disable faceshield blocking ADS or just don't ADS when using a faceshield.
The problem with Rogues in 3.5.0 is they take a looooong time to spawn, if you spawn nearby you probably have a about 5 mins to get in and out. I can maybe lower their spawns a small bit.
Ammo getting super expensive has been fixed, you're not using an old version of the mod are you?
Also, I don' t know how to take feedback saying it's too hard/expensive to buy items from traders so they disabled that feature but then find it too easy to get loot off of PMCs. I can't balance the mod against all possible config options, it's balanced around all the default options. I can look into toning down the stim chances on PMCs, but something like Arenaline and Morphine is vital if using the med changes. If you find the PMCs too easy to farm I recommend turning up the difficulty in the config or using a mod like POOP and configuring them to be hard.
My vision is for traders and the flea to be expensive and unreliable, and map loot to be a lot less common, and for PvE to be the main source of loot. To that end, ideally the AI would be very difficult.
The prices of things in SPT is based on live where what's valuable or isn't makes 0 sense realistically speaking, or even just with the changes I've made (like golden star). I'm not at a point where I can afford to manually change the cost of most items in the game, it's way too much of a time sink. If someone out there makes a mod to change the prices according to Realism's balance that would be great. Maybe for now I can lower the money you get from traders.
The JSON you shared is from an old version of the mod....tier 3 bears can't even spawn with the Vulkan anymore.....
I'll increase it to 60 for next version
