The only 2 enemies vulnerable to a single type of attack are DLC and you have your full arsenal by then.

I agree that the game is a bit weird during the second and third missions due to the limited tools you are given, but I think you might be exaggerating how the weaknesses work a bit.

Gamepass is going to continue betting worse until we end up with the mess that are streaming services right now.

I sincerely hope it fails.

This is a few days old but I might be able to help. Are you switching weapons or just sticking to a single one?

A single chainsaw gives you something like 20 shotgun slugs and a bunch of ammo for every single other weapon, you shouldn’t have ammo problems unless you are trying to kill a heavy demon with the assault rifle primary fire.
