I don't understand the hate you guys are expressing for external views !!!!
What do you care about what others do with their view settings
Your missions may block external views for all players joining your lobby (own sub and other subs), but the other lobby set up by that bloke from Johannesburg, South Africa, may have them turned on if he wishes.
How does it kill your precious immersion if you stick to your own words and never ever join his lobby...?
I'm curious.
Most sims I can think of do have external views as an option. I see no difference with Wolfpack.
As long as settings are clearly indicated in a lobby, it is fine.
Their choice, and your choice to jump in or bug off to your own lobby.
Cheers,
