You don't need to camp so much, because you don't need to be scared of people using the 3rd person camera to see you while you can't see them.Finally got the chance to try FPP and hated it as much as I expected to.
I think it, ironically, encourages camping because running out of cover when you have a reduced sense of what's around you is less preferable. For instance, I was in roz, and I knew there were a few other players in other houses, and i felt less inclined to leave my house because it's so much harder to quickly see where people are in all directions. It was much harder to determine exactly where they were so I just didn't want to leave cover.
It just felt restricted, weird, clunky with doors and loot, and annoying. I think it's not for me.
Now if he sees you, you can see him.
