Excellent mod, but I've got some questions about it.
It seems that it pushes up spawn rates massively? Or is there something else I'm not understanding? I feel like there's a non-stop stream of enemies on many maps. Factory is a good example. There's just never an end to enemies and because they follow gunshots, I feel like I never have any breathing space. Not to mention that every other raid the boss spawns on Factory and it's usually a one-hit kill if he finds me and there often isn't anything I can do to protect myself. I also feel like there are almost always raiders and guards lurking about, which I don't feel was an issue before I installed SAIN.
So I guess my question is, is it possible to slightly reduce spawn rates overall? Especially spawn rates for bosses. I'd like bosses to be a rare event and not something I run into every other raid. Failing that, it would be nice if not every single "tough" enemy honed in on gunshots all the time. It's obviously nice that they do and makes me think twice about picking fights, but it gets really predicable after a while and I would like to be able to pick a fight once in a while without it immediately turning into a whole-server deathmatch.
It would also be nice to be able to restrict how many chads can spawn per server. Every raid I keep running into enemies that require me to dump 2-3 mags (sometimes more) into them before they go down. I know this increases the "realism" by making it more like Live, but it's also kind of why I don't play Live. I don't want to never run into such enemies, but it would be nice if it happened less often. Especially considering once you start a fight with such an enemy, a bunch of others hone in on the location too.
I don't know how far this one is possible, as I haven't looked into modding myself, but it would also be nice if distant enemies who get into firefights with each other broke off the firefight after a while if they were locked in a stalemate. I don't want to disable distant AI entirely, because it's nice to hear distant fights, but the new AI means that NPCs are too "clever" to get killed by each other, so quite often they just spend the entire raid taking potshots at each other. It would be nice to be able to sneak through the resort and be able to listen to footsteps without all sound being drowned out by a distant firefight for the entire raid. 
Still, these are mostly minor niggles and I can't imagine playing without your mod ever again. It breathes so much life into the game and makes Tarkov feel dead when it's not being used! Thanks for this excellent mod!
PS it might be that your mod doesn't touch spawn rates at all, but it would be interesting to get to the bottom of why I'm constantly being flooded by enemies, especially on small maps like Factory.
