I do believe that current PVE settings (including ORP) are the best, especially for Extinction and Aberration (due to damn drakes and nameless who spawns inside base in blue biome). Don't want be afraid of corrupted dino dropped over my head. Can now build something beautiful without need to plant ton of X-plants which are looks awful. So I prefer to leave current settings as it is.
If people blocked some critical spawn points you can always report them and most likely admins will do smth to help.
