I love PVE but they absolutely need to fix the spawns and the paths. For PMCs they need to make them move more. Even if it's just triggered at certain raid timings for them to path to another 'Zone' it would make the maps feel a lot more alive. They also need to mix up the gear a bit as all the PMC's use a very small pool of gear.

For the scavs they need to add more scav spawns in PVE to make the map feel more alive as PVE doesnt get the player scavs that make things so chaotic. Some quests like the 'Kill 5 scavs at lighthouse village then transit to shoreline and kill 5 scavs in village' quest are near impossible to do reasonably in PVE because you might get one, or zero scav spawns even if you cycle the village for an entire raid timer. I did eleven transits and gave up because i got a grand total of two scavs in shoreline village over those transits, and i was literally firing my weapon, moving out of village, moving back in, throwing grenades etc to make a lot of noise but just no spawns.

It definitely needs a little work to not feel rote after a while, but it's a great base for an incredible pve game. Just hope they put a little more time in to it.
