Is there any way I can change the NAT type on my PS4 from type 3 (strict) into type 1 (open)?

Nope. Routers just help it split so more devices can be used. @Kevy is right.

It's all your ISP. I have 30mbps. My latency for league at night is like 200-400 milliseconds.

So almost half a second with no other devices connected. So in all things. Routers don't make internet speeds faster.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
