FWE increases the amount of creatures in each spawn am I right? Atleast that's how it has been since I installed the mod (and I've been playing for 4+ ingame days and big spawns still exist. Not using any Increased Spawns MMM plugins).
The thing is, for a First-Person Shooter noob like me it's just plain annoying. Not challenging, not immersive, just plain [censored] annoying. Having to fight 12 supermutants everywhere they happen to spawn forces me to rely on stealth, and avoiding buildings, cutting me out of places like Chrysylus building (where I just tried and failed).
This is mainly due to the fact that the increased spawns kills my FPS. The reason I moved to FWE in the first place that I couldn't increase spawns with MMM because of my PC being obsolete and slow so I wanted to have few but strong enemies. Now I have a crapload of superstrong enemies. My character is level 18 and is wearing leather armor and using SAKO RK-95 assault rifle with stats matched with FWE's Wanda AR.
Especially with followers this is extremely frustrating. I got Clover and she always gets decimated in less than four seconds. Not to mention the apparent increased intelligence of enemies, as one shot draws all the muties from within a mile to the location. It's pretty annoying, too. If I win a fight, then I can be certain that I just killed every single enemy in the building.
Just my two cents.. I really like this mod but this just drives me insane.. If I'm doing something wrong, tell me.
FWE doesn't touch the numbers of spawns, unless you're using the MMM / FOIP plugin, which builds in the basic increased spawns capacity. It's easy to change as Kai has mentioned.
Couple of other points:
1) Why would you expect leather armor to be a suitable armor to wear against 12+ super mutants, especially if you don't want to be sneaky. If you're wearing light armor and get into a tough situation, don't forget to use chems. It's pretty easy to max your DR with a handful of chems if need be.
2) Similarly, the Wanda AR, although a unique weapon, doesn't mean that it's by any measure the best weapon to use in all situations. I find the 5.56 caliber AR's to only be moderately effective against super mutant brutes/masters. You'll need to mix in some other weapons types to be effective. If you're specialized in small guns, use gauss rifles or sniper rifles, and aim for the head. Explosives are your fried as well.
3) Followers are dumb, but at the same time they are now set to essential. Get them some PA (you don't need to fit PA to followers), and they can take a lot of punishment if need be.
The next version of FWE will have an in-game menu that let's you customize many of the options and tailor the difficulty to your playstyle, so there is that to look forward too =)
Kai's tweak's to reduce damage might be worth a try, but in my view slightly reducing the damage changes the dynamic in a number of ways. Sure, you might live a little longer, but it also means that enemies take more time + bullets to kill. With less ammo to go around, that can present a new challenge. Just something to keep in mind =)
